Question

The electrophilic aromatic substitution of a compound $C_6{H}_{5}Y$ produces mainly a meta -disubstituted product. Among the following which one could be the substituent Y?

• A. $-N{H}_2$
• B. $-COOH$
• C. $-C{H}_3$
• D. $-OC{H}_3$

Answer 1

The correct option is B $-COOH$

Since, the product is meta-disubstituted product, the substituent Y is meta directing group. It could be $-COOH$ group. The remaining groups, $-N{H}_2,-C{H}_{3}and-OC{H}_3$ are ortho para directing groups.
