Q. Which of the following is correct with respect to -I effect of the substituents ? (R = alkyl)
A) $-NH_2 > -OR > -F$
B) $-NR_2 < -OR < -F$
C) $-NH_2 < -OR < -F$
D) $-NR_2 > -OR > -F$
Explanation
[Solution] -I effect increases with electronegativity (N < O < F), so both $-NR_2 < -OR < -F$ and $-NH_2 < -OR < -F$ are correct; both options were accepted. Answer (2) / (3).
