Q18 / 160 · AP EAMCET 2024 (21 May Shift 2) · Chemistry

Number of deactivating groups of the following is $-\mathrm{Cl},-\mathrm{SO}_3 \mathrm{H},-\mathrm{OH},-\mathrm{NHC}_2 \mathrm{H}_5,-\mathrm{COOCH}_3,-\mathrm{CH}_3$

A
4
Correct answer
B
3
C
2
D
1

Solution

The groups which withdraw electrons density from the benzene ring and make the benzene ring less reactive towards further electro philic substitution reaction. Deactivating group : $-\mathrm{Cl},-\mathrm{SO}_3 \mathrm{H},-\mathrm{COO} \mathrm{CH}_3$

Hence, the correct answer is option: 'B'.
