MCQ
Among the following compounds, which one has the shortest $C - Cl$ bond $?$
- A$H _{3} C - Cl$
- B
- ✓
- D
✓
Answer
Correct option: C.
c
In option $(3) C - Cl$ bond is shortest due to resonance of lone pair of $-Cl.$
In option $(3) C - Cl$ bond is shortest due to resonance of lone pair of $-Cl.$
Due to resonance $C - Cl$ bond acquire partial double bond character.
Hence $C - Cl$ bond length is least.
