Question

Which one of the following orders is correct regarding the $$-I$$ -effect of the substituents ?

A. $$ - N{R_2} < - OR > - F$$
B. $$ - N{R_2} > - OR > - F$$
C. $$ - N{R_2} < - OR < - F$$  
D. $$ - N{R_2} > - OR < - F$$
Answer :   $$ - N{R_2} < - OR < - F$$
Solution :
The electronegativity follows the order $$N < O < F.$$   So, due to electronegative character the order of $$-I$$ -effect is
$$ - N{R_2} < - OR < - F$$
