28481 Arrange the following labelled hydrogens in decreasing order of acidity

1

b > c > d > a

2

c > b > a > d

3

b > a > c > d

4

c > b > d > a

Explanation:

$\begin{matrix} O \\ | | \\ R - C - O H \end{matrix} > R - O H > R - C \equiv C H$
Reason: $\begin{matrix} O \\ | | \\ R - C - O^{θ} \end{matrix}$ stable by equivalent resonance.
Stable:
So answer is $b > c > d > a$
