MCQ
Order of acidic nature
- A$a > c > d > b$
- ✓$a > b > d > c $
- C$a > b > c > d$
- D$d > c > b > a$
✓
Answer
Correct option: B.
$a > b > d > c $
b
In compound $(a)$, $NO _{2}$ possesses the $- M$ effect at para position due to which it is highly acidic than other three compounds. The compound $(b)$ has intermolecular hydrogen bonding and it is less acidic than $(a)$. In compound $(d)$, there is absence of an electron donating group, due to which it is more acidic than compound $(c)$, which has electron donating methyl group. Therefore, the correct order of acidic nature is $a > b > d > c$
