alcohol is more acidic than acetylene.

#### Explanation:

consider an alcohol $C H 3 - C H 2 - O H$
and acetylene is $H - C \equiv C - H$

their conjugate bases are $C H 3 - C H 2 - {O}^{-}$ and $H - C \equiv {C}^{-}$.

since negative charge is more stable on O than C (electronegativity), so $C H 3 - C H 2 - {O}^{-}$ is LESS BASIC than $H - C \equiv {C}^{-}$ .{because more stable base are weak in nature}

thus the CONJUGATE ACID of $C H 3 - C H 2 - {O}^{-}$ is MORE ACIDIC than that of $H - C \equiv {C}^{-}$
i.e.,
$C H 3 - C H 2 - O H$ is more acidic than $H - C \equiv C - H$
