Addition on Conjugated Polyunsaturated Systems

Uh oh. More than one double bond? Makes things trickier. Make sure you understand the resonance involved in the intermediate! Addition on conjugated polyunsaturated systems will be less confusing if you follow Dave's arrows.

Boom. Clear, consistent, concise explanation. Thanks

[@uh6679]

You need that intro in all your videos! It rocks!

[@shinpaws1014]

was this the first time???

[@PunmasterSTP]

Conjugated polyunsaturated systems? More like "Cool videos and lots of students like them." Thanks for making all of them!

[@henkdevries2002]

This guy is a real legend!

[@user-eg4yd5ox7z]

you deserve more love

[@tinacao3660]

why the other double bond did not go through addition reaction?

[@PunmasterSTP]

I think that Dave only showed the reaction occurring at one double bond because the molecule was symmetrical. It would have been the exact same reaction had the reaction taken place at the other double bond.

4:15 he knowwwwws we hate it lol

[@PunmasterSTP]

Yeah keepin stuff simple is best.

[@sadhanahospital7584]

Thank you sir

[@rassimsimou1594]

Good

[@morgansampi5336]

good job thank youu

[@wi0lono]

Can we say that the addition of H-X on an alkene is not stereospecific in general or is that specific to this case?

[@ProfessorDaveExplains]

i think it's pretty safe to say that in general hydrohalogenation is not stereospecific, there may be counterexamples with special catalysts or something but i'm not aware of any such thing.

[@ustya4339]

How about 1,4-addition?

[@balaajisrin.k9365]

Sir,Are all the given in the above tutorial products major ??

[@ProfessorDaveExplains]

yep should be a fairly even distribution.

[@balaajisrin.k9365]

thank u sir
