Major product formed during the reaction between isobutyl bromide and benzene in presence of anhydrous AlCl3 is :
isobutyl benzene
t- butyl benzene
n - butyl benzene
no reaction
1,2 - methyl shift takes place in isobutyl carbonium ion
Major product formed during the reaction between isobutyl bromide and benzene in presence of anhydrous AlCl3 is (Benzne )
Statement-1 : Friedel-crafts reaction between benzene and acetic anhydride in the presence of anhydrous AlCl3 yields acetophenone and not poly substituted products. Statement-2 : Acetophenone formed, poisons the catalyst preventing further reaction.
