Question
CBSEENCH11008469

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

  • -NH2 <- OR < - F

  • -NR2 <- OR <-F

  • -NR2 >-OR>-F

  • -NH2>-OR>-F

Solution

A.

-NH2 <- OR < - F

-I effect increases on increasing electronegativity of the atom. So, the correct order of -I effect is

-NH2 <-OR < -F

Also, 

-NR2<-OR<-F
