Consider the following reactions:
Consider the following reactions: ‘A’ is:
‘A’ is:

Options

  1. ACH2=CH2C{H}_{2} = C{H}_{2}
  2. BCH≡CHCH ≡ CH
  3. CCH3−C≡C−CH3C{H}_{3} - C ≡ C - C{H}_{3}
  4. DCH3−C≡CHC{H}_{3} - C ≡ CH

Correct answer

D. CH3−C≡CHC{H}_{3} - C ≡ CH

Step-by-step solution

A reacts with Ag2OA{g}_{2}O , so it should have acidic hydrogen. This implies that the compound will be terminal alkyne.
