Question

Number of o/p-directing groups present on a benzene ring :

(a) $- N H_{2}$ (b) -CHO (c) -Br (d) $- OC H_{3}$ (e) -CN (f) $- C_{2} H_{5}$ (g) -COOH (h) $- NHCOC H_{3}$ (i) $- C F_{3}$ (j) -I

TestHub · Accepted Answer

Ortho/para-directing : − N H 2 ​ , -Br, − OC H 3 ​ , − C 2 ​ H 5 ​ , − NHCOC H 3 ​ and -I = 6. Meta-directing : -CHO, -CN, -COOH and − C F 3 ​ .
