MCQ

The two carbon atoms in acetylene are

A
$s{p^3}$ hybridized
B
$s{p^2}$ hybridized
✓
$sp$ hybridized
D
Unhybridized

✓

Answer

Correct option: C.

$sp$ hybridized

c
The carbon - carbon triple bond is only $1.20 \mathring A$ long. In the hybrid orbital picture of acetylene, both carbons are sp-hybridized. In an $sp$-hybridized carbon, the $2s$ orbital combines with the $2 px$ orbital to form two $sp$ hybrid orbitals that are oriented at an angle of $180^{\circ}$ with respect to each other.
