I have been stuck on this chapter for a week now but I learned it all in couple of hours with you 😭 you are a lifesaver thank you sooooo much please continue those amazing videos
You make organic chemistry reasonable and logical it's really alot more easier, you explain it in a reasonable way. Thank you for these amazing simple enjoyable science videos.
so glad to have your videos as my study guide. Wish you were the actual professor teaching this. So much more professional and helpful in much less time. loved your classes and videos over the years, Thanks for the CHM help!
Wow, you explain it so clearly! I've seen other videos, but yours is concise, super clear, and realized little things I didn't before. Amazing! I'm preparing for orgo next semester, so I'm glad you made these videos. 😊
I never understand that topic my school and college life. I always cheat my friends at that topic. But now in university life after watching your vodio am glad that this is very interesting topic you teach well. Sir i had a request will you teach me plz.?? I want to ask question whenever i want. So what is the solution of this problem
I would recommend mastering the fundamentals. That is isomers, resonance, hybridization, and Bronsted Acids/Bases. The most USEFUL thing you could do is get comfortable drawing bond-line/skeletal structures. Hope this helps.
These are alternative ways to name complex substituents...and I haven't seen them used much. Propan-2-yl is the same thing as an isopropyl group (common name) or 1-methylethyl group (systematic name). The '2' in propan-2-yl indicates that this substituent is 3 carbon substituent but is attached to the rest of the molecule via the 2nd carbon. You'll see such names used more commonly with certain functional groups like esters for example. So you might have 1-methylethyl butanoate a.k.a. isopropyl butanoate but which could also be called propan-2-yl butanoate. Similarly, butan-2-yl is the same thing as sec-butyl (common name) or 1-methylpropyl. It is a 4-carbon substituent that is attached to the rest of the molecule via the 2nd carbon. Hope this helps!
@@ChadsPrep Ah, that clears up everything. My teacher for the course (SCH4U - Ontario Grade 12 Chemistry) has mandated us to use the more IUPAC accurate name than the before IUPAC name. I've been stuck at this for a week but I couldn't stop thinking about this! Thank you - you are an amazing explainer
Hey Susan! If you look up those 2 compounds they are actually different. 3-isopropylheptane has an isopropyl group at carbon 3 rather than an ethyl group and is missing the methyl group at C2. Hope that helps!
So with saying "chlorocyclohexane" its understood that chloro is in the #1 carbon spot. For the second example can we not say "2-methyl chlorocyclohexane" since the chloro would have to be at the #1 spot? And so on "4-bromo-2-methyl chlorocyclohexane"? Thanks!!
Hey Joshua! I saw 1 professor accept such a name over a decade ago so I decided to do a little digging before answering. Unfortunately, my digging wasn't very fruitful. I'll start by saying that many organic compounds go by multiple names. Some are historical and some are the IUPAC systematic names. And sometimes IUPAC adopts common historical names as being proper!! And sometimes there are even multiple acceptable IUPAC systematic names (substituted benzenes come to mind). But even when this is the case there is a "preferred IUPAC name" or PIN. 2-methyl-1-chlorocyclohexane is the PIN in this case and I had trouble finding a specific IUPAC rule for a disubstituted cycloalkane that would even identify if leaving out the 1 is acceptable. So not helpful here, sorry. The exception to this that you'll learn later is if 1 of the two substituents is named as part of the parent chain then it will be at position 1 by default and the #1 is omitted from the name. 2-methylcyclohexanol for instance. Since the alcohol is named as part of the parent chain it has the priority and on a cyclic structure would be at position #1 by default and so it is omitted from the name. Hope this helps at least a little! Happy Studying!
@@ChadsPrepWOW! The reason I asked this is I was talking to my cousin a former ASU grad about OChem since I just finished it also. He told me he would’ve failed also just like me if it wasn’t for his TA. I told him I would’ve also if it wasn’t for your videos. He asked the name of the person I watch and told him yours and showed him a video of yours. He said “no way that’s HIM!!”. You helped my cousin become a doctor and are helping me on my way to become one also. Hope you have a great day God bless. (Also you’re still very recognizable to him haha)
That is fantastic Ricky! I can't tell you how much I miss working with students at ASU...still even live a few miles from campus. Best wishes on the journey and pass on my congratulations to your cousin! May God bless you in return!
With only 1 substituent it would have to be at position 1. But with multiple substituents it gets confusing. But I did see one professor on one occasion over a decade ago allowing students to do exactly as you suggest. But I haven't seen it again. I actually invested some time earlier this year to answer this exact question. I looked up the IUPAC rules themselves (instead of a textbook's version of them) and couldn't find it addressed specifically, so I'm going to keep teaching it as presented in all the major textbooks with which I'm familiar. Happy studying!🙂
I felt doomed and ready to drop my class. Your videos gave me A HUGE HOPEFUL RESOURCE! Thank you! I get it waaay better.
Glad to hear it - Happy Studying!

You're welcome, S.A. - Glad the video helped!
best teacher on youtube rn love the simple way you teach. everyone make this topic so complicated love from india we want more series like this
Thanks for the awesome feedback!
GOD-LIKE!! Thank youuuuuu!! As a pre-med, this videos helped me a lot! I use them to review for exams in my OG Chem class.
Glad the channel is helping - Happy Studying!

Hi, could you help me explain how some subsitutants are called propan-2-yl or butan-2-yl?
These are alternative ways to name complex substituents...and I haven't seen them used much.
Propan-2-yl is the same thing as an isopropyl group (common name) or 1-methylethyl group (systematic name). The '2' in propan-2-yl indicates that this substituent is 3 carbon substituent but is attached to the rest of the molecule via the 2nd carbon. You'll see such names used more commonly with certain functional groups like esters for example. So you might have 1-methylethyl butanoate a.k.a. isopropyl butanoate but which could also be called propan-2-yl butanoate.
Similarly, butan-2-yl is the same thing as sec-butyl (common name) or 1-methylpropyl. It is a 4-carbon substituent that is attached to the rest of the molecule via the 2nd carbon.
Hope this helps!
@@ChadsPrep Ah, that clears up everything. My teacher for the course (SCH4U - Ontario Grade 12 Chemistry) has mandated us to use the more IUPAC accurate name than the before IUPAC name. I've been stuck at this for a week but I couldn't stop thinking about this! Thank you - you are an amazing explainer
12:43 instead of saying 3-ethyl-2-methylheptane, why can't it be 3-isopropylheptane? That seems easier

I typed "2-methyl-chlorocyclohexane" into some IUPAC programs and it successfully brought up the same structure.
Hey Joshua! I saw 1 professor accept such a name over a decade ago so I decided to do a little digging before answering. Unfortunately, my digging wasn't very fruitful. I'll start by saying that many organic compounds go by multiple names. Some are historical and some are the IUPAC systematic names.

Hey so random question I hope you see. But did you ever TA OChem at ASU? A bit ago
Sure did Ricky! But more than a bit ago. I'll take it as a compliment that I'm still recognizable! ;)
@@ChadsPrepWOW! The reason I asked this is I was talking to my cousin a former ASU grad about OChem since I just finished it also.

@@ChadsPrep thanks so much! Yeah I’m following in his footsteps by going to ASU and everything lol. You’re great have a great rest of your day!!
Chad when you finish writing on the board, if you could please stand a little closer to the door, so that we can take a screenshot of the board
Thanks for the suggestion - Happy Studying!
Why do we add the 1-chloro to 1-chloro-2methylcyclohexane? Why isn’t it just chloro like the example before?
With only 1 substituent it would have to be at position 1. But with multiple substituents it gets confusing. But I did see one professor on one occasion over a decade ago allowing students to do exactly as you suggest. But I haven't seen it again. I actually invested some time earlier this year to answer this exact question.

@@ChadsPrep Thank you Chad. My gf had you as a TA so it's been very helpful using your videos in advance of taking the course where I am.
It's exam week, so you know what that means? Fire up the Chad's Prep!
Study, study, STUDY --- and score BIG! Hope you do well!
Thank you.
