If the left test tube contains an alkane, there is no mixing either. The bromine water forms two layers (hardly visible), with bromine dissolved in the upper alkane layer as well. If you would have shaken the left t.t. you would have noticed that most of the bromine prefers the alkane as a solvent (both non-polar).
damn this was 9yrs ago... and now im studying for my gcses, so js wanted to ask, hows life man, haha! its been 9 yrs since u commented and whatsup now, watchu doing? and hows everything?
The bromine atoms add to the carbons in the double bond, they don’t “replace itself”. A vicinal dibromide forms. But most likely a bromohydrin forms due to water being the solvent and thus the nucleophile in higher concentration (sorry, my phone died while I was typing this comment, and it still posted. I forgot I was typing it once that happened until someone liked my comment).
Check the caption of the video :) in a short period of time, bromine will "airify", essentially go into the air. Bromine, Br2, can be extremely damaging to our respiratory system if inhaled. Hope this helps.
I don’t remember exactly but I used something polar enough to mix with water, like ethanol. Although alcohols can technically react with bromine, it would require acidic conditions and probably heating. So that’s why it mixed with the bromine water but still didn’t react.
when bromine was added to alkane, do you mean NO reaction occur at all?or is it occur at very minimum amount? coz how should halogenation of alkane be explained?i'm baffled.thx a lot if u can explain this
You are correct, alkanes can be halogenated. However, such a reaction requires a source of energy such as uv light to start the reaction. The uv light allows the halogen-halogen bond to be broken so the free radicals can react. Hope this clears up any confusion!
+Gooferking Science I had the same question thanks a lot bc my book says that even alkanes will make bromine colorless so I was wondering how could this test work but now I know you don't have to provide uv for this test to work

C6H14(l) + Br2(l) -> Doesn't act
C6H12(l) + Br2(l) -> C6H12Br2(l)
Br2 is a red liquid but C6H12Br2 is a colorless liquid.
Thanks a lot
whose here because there orgo lab is making them watch these videos?
since there are two layers in the alkene reaction with bromine, i wonder whether the water is the layer above or under the products of the reaction?
that's so cool man! keep it up!
What alkane was used??
why is this experiment banned at schools in my area?

May I know what materials are exactly needed for this experiment? I would appreciate it...
Thankyou so much! My chemistry teacher's shit and this was very helpful.

I always did this lab but now due to online teaching your video is our help Thank you
That’s great! I’m happy this video helped!
For alkynes ?? Is it d same as alkene ??? Cozzz it's a triple bond which can get replaced??? Is dat right
Thanks for the experiment.🙏
Does heptane change the color of the black oil?
C6H10 + 2 Br2 -> C6H8(Br2) + 2HBr?
what happens when exposed to sunlight?
Thank you! Your videos are always interesting too!
Yep! I used turpentine (mainly pinene) as the alkene like they recommended.
Hey.. this is cool.. I am gonna use your video for lab presentation. Thanks a lot :)
Thank you! This was very helpful
Not gonna explain it?, you just did..
I said “I’m now going to explain” not “I’m not going to explain”.
what is the traslucent layer above the haloalkane in the middle test tube?
Damn brother great explanation
the first is just water because if it was an alkane the bromine water don't mix
I don’t remember exactly but I used something polar enough to mix with water, like ethanol. Although alcohols can technically react with bromine, it would require acidic conditions and probably heating. So that’s why it mixed with the bromine water but still didn’t react.
Does it form vic dibromide

how much bromine do you use?
I saw you posting about this on sciencemadness!
thanks dude! from caldedale college!
Woops I was logged in as Nathan Marshall not Goofeking.... I am not sure why they gave me two accounts.
Umm what about CCl4?
Lol Ncert ppls
@@tanishmbbs lol a guy who thinks he is higher cause he doesn't have NCERT
@@nuhh69 are bhai me bhi vahi dekne aya tha CCl4 ka kya kam
@@tanishmbbs sorry mate, I pre-assumed, I have seen people having the behavior I mentioned
Thank you so much
Anyone know the equation involved in this reaction ?
C2H4(ethene) + Br2 forms BrCH2-CH2Br that is vic-Dibromide which is colourless
Thanks I understood very easily
Thanks this was really helpful .
tomorrow i have chemistry exam. thanks
Thanks. It helped a lot
A good video hope more videos like this thank you 👍🏻👍🏻👍🏻
thank you so much !
This represents the unsaturation of alkenes
very dangerous reaction
