Options:
A) $ \text{-N}{H_2}\text{-OR-F} $
B) $ \text{-N}{R_2}\text{-OR-F} $
C) $ \text{-N}{H_2}\text{-OR-F} $
D) $ \text{-N}{R_2}\text{-OR-F} $
Show Answer
Answer:
Correct Answer: C
Solution:
I effect increases on increasing electronegativity of atom.
So, correct order of -I effect is $ \text{–N}{H_2}\text{–OR–F} $ .
Most appropriate Sol. is option [c],
However option [b] may also be correct Sol.
