Which of the follwing compounds will undergo Friedel Creadfts alylation with faster rate?

Answer»




Solution :More the `EDG` faster is the `SE` reaction or `F.C` reaction.
But `ED` power of `(-NH_(2))` (by resonance) is greater than `(-CH_(3))` (by hyperconjugation). But anilline does not undergo `F.C` reaction.
Therefore, in (a) three `H.C` STRUCTURES.
In (c) one `H.C` STURCTURES.
in (d),`(-NO_(2)) EWG, F.C` reaction does not take place.
So in (b) `F.C` reaction is FASTED.
