Q.

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

  1. A

    – NH2< – OR < – F

  2. B

    – NH2> – OR > – F 

  3. C

    – NR2< – OR < – F

  4. D

    – NR2> – OR > – F

Solution

–I effect increases on increasing electronegativity of atom. So, correct order of

–I effect is –NH2 < – OR < – F.
