Question

Acetylenic hydrogens are acidic because
(a) Sigma electron density of C – H bond in acetylene is
nearer to carbon, which has 50% s-character
(b) Acetylene has only open hydrogen in each carbon
(c) Acetylene contains least number of hydrogens among
the possible hydrocarbons having two carbons
(d) Acetylene belongs to the class of alkynes with
molecular formula, CₙH₂ₙ₋ ₂.
