Identify the alkyne formed by reaction of calcium carbide with water?

Options

  1. AEthyne
  2. BPropyne
  3. CBut-1-yne
  4. DBut-2-yne

Correct answer

A. Ethyne

Step-by-step solution

The reaction between calcium carbide and water produces ethyne gas according to the balanced equation: CaC₂(s) + 2H₂O(l) Ca(OH)₂(aq) + C₂H₂(g) . Ethyne ( C₂H₂ ) is recognized as the simplest alkyne, featuring a carbon-carbon triple bond. The correct answer is A.
