Question #7a381

Answer 1

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`
