Question

Predict the major product for the following reaction CH CH2CI AlCl3 O2N ON 02N H2 H2 02N 02N H2 H2 IV

Answer 1

option IV is the major product.

Explanation: Reaction of substituted benzene ring with alkyl halide and AlCl3 is called Friedel-Craft's alkylation. Friedel-Craft's alkylation occurs on more electron rich benzene ring. -NO2 is electron withdrawing group and decreases electron density on benzene ring. so electrophilic aromatic substitution occurs on other benzene ring which do contain -NO2 group.
