MCQ
The two carbon atoms in acetylene are
- A$s{p^3}$ hybridized
- B$s{p^2}$ hybridized
- ✓$sp$ hybridized
- DUnhybridized
✓
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.
