MCQ
Shortest $C-C$ bond length is present in
- A$C{H_3} - C{H_2} - C{H_3}$
- B$C{H_3}C{H_2}C{H_2}C{H_3}$
- C$C{H_2} = CH - CH = C{H_2}$
- ✓$CH \equiv C - C \equiv CH$
✓
Answer
Correct option: D.
$CH \equiv C - C \equiv CH$
d
(d) Bond length decrease with increase in Bond order. Hence triple bonded carbon has minimum bond length.
(d) Bond length decrease with increase in Bond order. Hence triple bonded carbon has minimum bond length.
$C -C$ bond length = $1.54 \,\mathop A\limits^o $
$C = C$ bond length = $1.33\,\mathop A\limits^o $
$C$ $ \equiv $ $C$ bond length = $1.22\,\mathop A\limits^o $
