Vedclass · Answer

(B) The given molecule is a substituted benzene derivative. $E.A.S.$ reactions occur at positions that are most electron-rich due to the activating effects of substituents.In this structure,the alkyl groups (specifically the tert-butyl group and the fused ring system) are electron-donating by the inductive effect $(+I)$.Position $c$ is ortho to the tert-butyl group,but it is sterically hindered.Position $b$ is meta to the tert-butyl group and para to the fused ring system.Position $a$ is para to the tert-butyl group and meta to the fused ring system.Considering the electronic effects and steric hindrance,the most favorable position for $E.A.S.$ is position $b$,as it is relatively less sterically hindered compared to $c$ and is activated by the electron-donating groups present in the ring.

Identify the position where $E.A.S.$ (Electrophilic Aromatic Substitution) will take place.
