( C - Cl ) bond in chlorobenzene a comparison to ( C - Cl ) bond in methyl chloride is
Options
- Alonger and weaker
- Bshorter and weaker
- Cshorter and stronger
- Dlonger and stronger
Correct answer
C. shorter and stronger
Step-by-step solution
Because of (+R ) effect of Cl-atom with the ring, ( C - Cl ) bond in chlorobenzene gets a double bond character and it becomes shorter and stronger than the ( C - Cl ) bond of in methyl chloride ( ( CH ₃- Cl ) ), which does have such effect.
