The hydrogen atoms present in acetylene molecule are
general-sciencechemistry
- Aacidic
- Bbasic
- Cboth acidic and basic
- Dneutral
Explanation
The two hydrogen atoms of acetylene are attached to triply bonded carbons and are distinctly acidic, with a pKa around 25, forming acetylide salts with strong bases. They are not basic or neutral. Hence the hydrogen atoms in acetylene are acidic.
