Question

Which one of the following orders is correct
regarding the —I effect of the substituents ?
(a) —NR₂ <— OR >—F
(b) —NR₂ > — OR >—F
(c) —NR₂ <— OR <—F
(d) —NR₂ >— OR <—F

Answer 1

Answer:

i hope c is a write answer

Answer 2

(c) —NR₂ <— OR <—F

Explanation:

The electronegativity of F, O, and N follows the order: N < O < F. So the the negative inductive effect of - NR2, -OR and -F too follows the same order. So -NR2 has the least electronegativity while - F has the most electronegativity among the given list.

Hence —NR₂ < — OR < —F.

Option C is the answer.
