AQA 3.5 Alcohols REVISION

[@TsukkiSenpai727]

This guy is hella hella underrated thank goodness this teacher posts these super helpful videos!

[@user-lr8op6qx7p]

Thank you so much - you're truly saving my life right now with your teaching and explanations

[@arsalansakhawat356]

thank U Sir . i am loving this revision series ✔

[@AlleryChemistry]

You're welcome. Hope revision is going well

@ 11mins the bp of CYCLOHEXENE is 83 c, hence cyclohexene will be in the collection tube.

[@FHGRaja]

Could you please do a video on the practical procedures ? Or practical methods (condensed)

[@AlleryChemistry]

Will look into it.

8:12 it says dehydration of alkene?

[@Scizzq]

Yh i noticed that aswell 😂

[@nifemio8847]

exactly

[@cardibisover]

28:14 Why does central carbon in propanone have 5 bonds

[@EMB-on9pb]

Hey im wondering the same, did you figure it out?

[@samuuu1996]

its a mistake; read description@@EMB-on9pb

[@sussybaka8605]

im cooked

[@sameernaveed2238]

Im confused. In the alkenes video you said that the alcohol is formed from the alkyl hydrogen sulphate using cold water. In the alcohols topic you are saying steam is used and not cold water?

[@zaynbye4275]

the reaction conditions for both are different so the mechanisms are slightly different

[@sadiyaahmed4255]

Hi there, thank you so much for the video really helpful. Just wanted to ask in regards to the making of cyclohexene. When the reactants are boiled to 83, is it not because the product of cyclohexene has a bp of 83?

[@rashidbinhendi653]

Yea ur right I think it was a mistake, as cyclohexene has a bp of 83 not cyclohexanol as it has a bp of 161.8 and it wouldn't make sense to be distilling for cyclohexanol

[@Ffggglelwlqowqqoves2]

When you draw the dehydration mechanism do you need to show the sulphuric acid reacting fully.or do you just used the H+?

[@absjane3696]

Both are accepted. I just use H+ because it’s easier

[@Masowe.]

9:11 I better get ready for that

[@legendlegend4459]

do we have to know how to draw the distillation and reflux diagram?

[@uchihaitachiofthesharingan]

yes

[@mattharris1930]

re: dehydration of non- primary alcohols with acid catalyst are the 2 different products that r formed just as likely or is there a major and minor? i dont think there is, so r both just as likely to be formed??

[@anasmezouar4678]

depends if you're oxidising with excess oxygen or excess alcohol

[@AM-hn7gj]

There is a major and minor cos one has a primary carbocation intermediate and the other has a secondary carbocation intermediate.

[@arianaribeiro3913]

@@AM-hn7gj aren’t they just as likely because it’s the same carbocation just the adjacent hydrogen used is different so the double bond ends up on a different carbon?

[@sianlopez]

Who else watching this for next year fucken MOCKKKSSSS!!!!!!

[@hussainhammed2942]

are there any revision videos for the year 2 content?

[@jayuchihaa]

24:54 the middle carbon has 5 bonds?...

[@AlleryChemistry]

Hi, This is an error as carbon only has 4 bonds. Cheers!

[@beezoid2479]

very nice sir i will get an a star now

I hope you do. 👍
