Which of the following has the shortest C - C l bond?
Options
- AC l - C H = C H 2
- BC l - C H = C H - N O 2
- CC l - C H = C H - C H 3
- DC l - C H = C H - O C H 3
Correct answer
B. C l - C H = C H - N O 2
Step-by-step solution
Due to –M effect of − NO 2 and + M effect of Cl more D.B. character between C – Cl bond. So shortest bond length.
