I have my organic chem test tmrw and I know there’s gonna be questions abt boiling point and I didn’t get it and I was so stressed. Not only did this help me understand but it was also so weirdly calming. Thank you so much
Its good job sir. I can easily understand about the boilling point in organic molecules. This vidio is more helpful... thnk u very much sir and god bless you...
Hello, when we are comparing organic compounds with halogens, you said that bigger atoms would result in higher boiling points because of the increased London dispersion forces. Does this mean that the effect of the halogen's electronegativity is negligible? I thought that the one with fluorine would have a higher boiling point than the one with bromine because fluorine is more electronegative and would cause a greater dipole moment.
I think that since dipole dipole interaction is stronger than Vander Waals interaction, the boiling point should be decreasing in the order of F --> Cl --> Br --> I.
thats right but here he is taking the size of the atom first before considering the electronegativity reason being similar to resonance structure. the charge of the anion is more stable to chlorine than fluorine tho fluorine is more electronegative but chlorine is larger and can stabilize the charge more than the fluorine. i hope that helps?
@@Sanyakhan803 so does that mean that for an h-bond to occur, there must always be an intramolecular force between hydrogen and Nitrogen, Oxygen or fluorine?
@@ThriveNow123 if there is a O-H, N-H etc bond IN a molecule, there is hydrogen bonding between molecules. For example in an aldehyde, -CHO, oxygen isnt bonded to hydrogen. So there is no hydrogen bonds. Hydrogen bonds exist when there is a large dipole only.
Given the following pairs of organic compounds, underline which one boils at a higher temperature and explain why it is so. benzene, benzaldehyde propan-2-ol, propan-1-ol toluene, phenol butyl alcohol, sec-butyl alcohol
At 12:15, doesn't NH2 provide 2 H-bonding sites? Wouldn't this result in more H-bonds in a mixture and therefore a higher boiling point than for the compound with the singe -OH hydrogen bonding site? I understand that electronegativity plays a role, but isn't having 2 H-bonds also a significant factor?
to see how big an atom is, do we look at the atomic number or the radius? The radius can be lower for heavier atoms relative to a atom with lower atomic number
both water and amine have 3 h bonds each.coz no of h = lone pairs+no of h atom attached to F or O or N.so we have to compare polarity of bond for further confirmation.
I'm a bit confused Doesn't fluorine have a greater electronegativity so it can create a dipole dipole interaction that is much stronger than the other halogens in methyl alkines, hence is it supposed to have a greater bp?
why primary alcohol has higher b.p than primary amine? I thought amine would have higher b.p since it has 2 H which can form lot more hydrogen bond compared to primary alcohol.

I know rth ,,going through the same
@@rohithbimal5335 Yeah I have my test in 2 days, this is such a good vid
lmao same, my midterm's in 12 hrs, worth 50% of my grade@@simonvutov7575
Bro I have a midterm test for o-chem next week. Wish me luck my friend tomatoh1629
you are the best chemistry tutor i have ever come across on the internet. thank you for making things easy for me.
You should open your own institute bro..
😂😂 because this guy is so good 🥹❤️❤️
I agree
man if I ever have enough money. I will buy all of his videos in patreon and watch them non stop.
THANK YOU for SAVING MY LIFE.
Same
I dont even attend lectures,for 3hours I just watch your 20min videos ad I got A...God bless you tutor✊
I was searching everywhere on the internet for what you explained on this video! Thank you so much!!! Everything is much clearer now :)
Thank you! This explained more than my textbook and my school tutors!
I have my ochem final tomorrow and this re-upload is great!
This is the man that’ll be the reason I do any good on my chem exam on Monday!
Update: I failed the exam but only by half a mark
@@oliviacorbeil6230 you will get the revenge in the next exam bro
this guy is great man i got all my doubts cleared related to this topic
You are superior to any chemistry professor earning hundreds of thousands of dollars.
I'm studying for my quiz and this video has been so helpful! TYSM!!!!!
Its good job sir. I can easily understand about the boilling point in organic molecules. This vidio is more helpful... thnk u very much sir and god bless you...
when i get my A on chemistry, its all gonna credit to you, love you xx
Best video for boiling point comparison
Great! For those studying hydrocarbon Alkanes specifically, you only have to count the number of bonds.
14:30 also, look at the structure of primary amine, it’s linear!
this man right here changing the world
Really like your video. If i have questions regarding a chemistry mechanism, I will always click on your video for it
Thank You very much. You cleared a lot of misconceptions from my mind.

He said that electron cloud of Bigger atom will spread more due to which the interaction between the molecules increases
In the comparison between ethyl chloride and ethyl bromide, wouldn't the polarity of Cl be considered??
Thank you! Just in time for my Orgo midterm
Man you are a hero,a savior
This was so easy to understand.
Yohhhhh dude... Thanks bruh... Yohhh thanks a lot shem❤❤
You are a miracle bro
Arent there hydrogen bonds @4:08 as well? Between Hydrogen and Oxygen?
No because H is not directly attached to O. There not a high dipole in C-H bonds.
@@Sanyakhan803 so does that mean that for an h-bond to occur, there must always be an intramolecular force between hydrogen and Nitrogen, Oxygen or fluorine?
@@ThriveNow123 if there is a O-H, N-H etc bond IN a molecule, there is hydrogen bonding between molecules. For example in an aldehyde, -CHO, oxygen isnt bonded to hydrogen. So there is no hydrogen bonds. Hydrogen bonds exist when there is a large dipole only.
@@ThriveNow123 And yes, hydrogen bonds only occur in between two molecules, between O/N/F and H.
@@Sanyakhan803 oh ok jazakallah
Here in 2021 prepping for Organic Chem class 👌🏼
Thanks for explaining it easily and quickly
damn dude u teach so well .......u aced it up to be honest
Please do a vedio on freezing point
thank you so much. It was so helpful💙💙💙💙💙💙
Good bahut ache.. Wah.. Bahut badiya.. Gajab
plz plz also make a video on topic:-MELTING POINT and also include SYMMETRICAL PACKING concept of determining melting point...
doing my hsc tomorrow. thanks for this video.
Given the following pairs of organic compounds, underline which one boils at a higher temperature and explain why it is so.
benzene, benzaldehyde
propan-2-ol, propan-1-ol

Thank youuuuu⚘⚘⚘⚘ it really really reallly made things way more clear!!!!!!!!!

I understand that electronegativity plays a role, but isn't having 2 H-bonds also a significant factor?
In amines there aren't 2 H bonding sites, only one of them undergoes H bonding,
and hence electronegativity plays a vital role.
You always get me covered thanks bro
This video helped a lot! Thank you so much!
Amazing already huge portions coverd😜😜
So basically the more hydrocarbons an alkane group has the higher the boiling point.
Thank you so much. You teach way better than my college professor lol
to see how big an atom is, do we look at the atomic number or the radius? The radius can be lower for heavier atoms relative to a atom with lower atomic number
I love organic chemistry
Thank you. School is closed due to freezing temperatures and our prof says "go teach yourself O Chem, lab report due Tuesday" LOL not fun
extremly helpful...Thanks for comparing the B.P of organic chemistry!
Thanks 🙏♥️🇮🇳
at 12:31 there are 2 h bond in NH2 but why it has less b.p?
both water and amine have 3 h bonds each.coz no of h = lone pairs+no of h atom attached to F or O or N.so we have to compare polarity of bond for further confirmation.
YOU SERIOUSLY ARE THE BEST!!!! WORK LITTLE AND EARN A LOT BRO :)
Can u explain what happens in primary, secondary and tertiary aniline?
Thank you very much Sir.
A big thanks.............
Just thank you sir
Thankyou for this video
Thank you so much
Best video
Bro I was not able to understand this shit in 2 years 11th grade and 12th grade
Finally got it
Thank you sir
00:27 nice
Thank you!!
Thank you so much sir
thank you
thank you i love you
Cl is more electronegative than Br but for one example we didn't use electronegativity but used atom size to compare?
Bcz they are halogen?
What is the atomic mass of boron from the atomic boiling point of carbon?
I'm a bit confused
Doesn't fluorine have a greater electronegativity so it can create a dipole dipole interaction that is much stronger than the other halogens in methyl alkines, hence is it supposed to have a greater bp?
Naa, you have to consider the forces of attraction existing between their molecules
... help me understand
Does a higher boiling point mean a molecule is more stable?
why does butene have a lower boiling point than butane?
thanx for saving me
That was lit.
why primary alcohol has higher b.p than primary amine? I thought amine would have higher b.p since it has 2 H which can form lot more hydrogen bond compared to primary alcohol.
Thanks Sir
He teaches too detailed 11:18 he compared the size and also he draw them with corresponding colors, OMG
Jabardast hai.
Thanks
“let’s compare hand sizes”
i can’t i have organic chemistry final. let’s compare boiling points of organic compounds instead
how is c2cl LDF?
Legend
0:26 nice
how is he figuring out these BP degrees ? Am i missing some video I should watch ?
no he just happened to know it
Not the level of content i was wondering
But i know you are op

Organic Chemistry Tutor supremacy
how about the boiling point of alcohols which the OH in different carbon?
Ah Ah JJ, ur merch iz doo expnesive for me
Good morning haa 15:20
melting point?
me when the video started and he drew zigzags :o
make a melting point video
I love you
Can I pay you instead of paying my instructors at uni? Bro...
I. Love. You.
my thing is, how did he know the degrees?
Experimental values.
who's come here for getting of rid of it..😂
Can you answer my papers?
I thought CH3CHO and CH3CHOH were the same😂
