Easy MCQ +4 / -1

The acidity of terminal alkynes is due to:

  1. A sp hybridised carbon Correct answer
  2. B sp² hybridised carbon
  3. C sp³ hybridised carbon
  4. D High bond dissociation energy

Solution

sp C has 50% s-character → holds electrons closer → more acidic. Terminal alkynes (R-C≡CH) react with Na to give acetylide ions.
