Which of the following is correct with respect to — I effect of the substituents ? (R = alkyl)
— NH2 > — OR > — F
— NR2 < — OR < — F
— NH2 < — OR < — F
— NR2 > — OR > — F
As we learnt that
-I - effect (Negative inductive effect) -
Those atoms or group of atoms having more tendency to displace e - towards itself as compared to Hydrogen atom is called Negative Inductive effect
- wherein
Based on electronegativity
— NH2 < — OR < — F
or
— NR2 < — OR < — F
Option 1)
— NH2 > — OR > — F
This is incorrect.
Option 2)
— NR2 < — OR < — F
This is correct.
Option 3)
— NH2 < — OR < — F
This is incorrect.
Option 4)
— NR2 > — OR > — F
This is incorrect.
