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

whose here because there orgo lab is making them watch these videos?
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
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!
Thankyou so much! My chemistry teacher's shit and this was very helpful.

that's so cool man! keep it up!
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?
Thanks for the experiment.🙏
Thank you! Your videos are always interesting too!
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”.
Damn brother great explanation
May I know what materials are exactly needed for this experiment? I would appreciate it...
why is this experiment banned at schools in my area?

Yep! I used turpentine (mainly pinene) as the alkene like they recommended.
Thank you so much
Hey.. this is cool.. I am gonna use your video for lab presentation. Thanks a lot :)
Thanks I understood very easily
For alkynes ?? Is it d same as alkene ??? Cozzz it's a triple bond which can get replaced??? Is dat right
thanks dude! from caldedale college!
What alkane was used??
I saw you posting about this on sciencemadness!
Thanks this was really helpful .
Thank you so much 😌
A good video hope more videos like this thank you 👍🏻👍🏻👍🏻
the first is just water because if it was an alkane the bromine water don't mix

Thanks. It helped a lot
what happens when exposed to sunlight?
Does heptane change the color of the black oil?
C6H10 + 2 Br2 -> C6H8(Br2) + 2HBr?
This represents the unsaturation of alkenes
Woops I was logged in as Nathan Marshall not Goofeking.... I am not sure why they gave me two accounts.
Thanks
tomorrow i have chemistry exam. thanks
what is the traslucent layer above the haloalkane in the middle test tube?
Nice video
how much bromine do you use?
reallly helpful thanks
We are watching in chemistry class
very dangerous reaction

Does it form vic dibromide
wow.thankyou❤️
Anyone know the equation involved in this reaction ?
C2H4(ethene) + Br2 forms BrCH2-CH2Br that is vic-Dibromide which is colourless
Good bro
