MCQ
Which one of these shows least -I effect:
- A$−\text{OH}_2^+$
- B$−\text{NH}_3^-$
- C$−\text{NO}_2$
- D$−\text{F}$
✓
Answer
- $−\text{F}$
Explanation:
Since + charge is more electronegative than neutral atom therefore correct order is
$−\text{OH}_2^+$>$−\text{NH}_3^-$>$−\text{NO}_2$>$−\text{F}$. Hence least $−\text{I}$ effect is shown by $−\text{F}$.
