MCQ
The organic compound having a triple carbon-carbon covalent bond, is:
  • ✓
    $C _3 H _4$
  • B
    $C _3 H _6$
  • C
    $C _3 H _8$
  • D
    $C _4 H _{10}$
✓

Answer

Correct option: A.
$C _3 H _4$
(a) $C _3 H _4$
Explanation: The only compound containing triple bond or triple carbon-carbon bond is $C _3 H _4$, also known as propylene. Its structure can be represented as:
$H_3 C-C \equiv CH$
$C _3 H _6$ is an alkene that contains a double bond, while $C _3 H _8$ and $C _4 H _{10}$ are alkanes that contain only a single bond.
