MCQ
The bond length between $s{p^3}$ hybridised carbon atom and other carbon atom is minimum in
- APropane
- BButane
- CPropene
- ✓Propyne
✓
Answer
Correct option: D.
Propyne
d
The $C - C$ bond length $=1.54\, \mathring A, C = C$ bond length $=1.34\, \mathring A$ and $C \equiv C$ bond length $=1.20 \,\mathring A$. Since propyne has a triple bond, therefore it has minimum bond length.
