alcohol is more acidic than acetylene.

Explanation:

consider an alcohol #CH3-CH2-OH #
and acetylene is #H-C-=C-H#

their conjugate bases are #CH3-CH2-O^- # and #H-C-=C^-#.

since negative charge is more stable on O than C (electronegativity), so #CH3-CH2-O^- # is LESS BASIC than #H-C-=C^-# .{because more stable base are weak in nature}

thus the CONJUGATE ACID of #CH3-CH2-O^- # is MORE ACIDIC than that of #H-C-=C^-#
i.e.,
#CH3-CH2-OH # is more acidic than #H-C-=C-H#
