  polyene

• Flying grenade

  6 Oct 16, 01:29

  Polyenes are poly-unsaturated organic compounds that contain at least three alternating double and single carbon–carbon bonds. These carbon–carbon double bonds interact in a process known as conjugation.

  what product will form when ester, amides, acyl halides react with 24dnph, Nu Sub to give what?

  why is OH- hydroxyl group a better leaving group than carbanion R- or hydride H- ? 

  OH- is also a strong nucleophile like R- and H- right ?

   

   

  cks say due to the above reason, aldehydes and ketone undergoes nu add, carboxylic acid undergo nu sub

  how do we know which substituent group is dominant?

  and in this case cks writes weakly activating CH3 groups dominate the strongly deactivating NO2 group ?

  should be 2 methyl groups.

   

  what about 2 ethyl groups compared to 3 methyl groups?

  Draw out the mechanism then you'll know.

  Draw the resonance contributors to substantiate your claim.

  Irrelevant, because in such scenarios other factors (figure them out yourself, go ask your school teacher or private tutor, and don't reveal them on the forum, edart sterces) will outweigh inductive effects.
