Question

Which of the following is correct with respect to -I effect of the substituents? (R = alkyl)

(a) -NH₂ < -OR < - F

(b) -NR₂< -OR < - F

(c) -NH₂ > -OR > - F

(d) -NR₂ > -OR > - F

Answer 1

The correct option is: (a) -NH₂ < -OR < - F

(b) -NR₂< -OR < - F

Explanation:

-I effect increases on increasing the electronegativity of atom.

. ^.. -NH₂ < -OR < - F  -I effect

Also, -NR₂< -OR < - F  -I effect
