Among the following species, the most stable carbonium ion is
Options
- AC ₆ H ₅ + C HC ₆ H ₅
- BCH ₃ + C H ₂
- CC ₆ H ₅ + C H ₂
- DC ₆ H ₅ CH ₂ + C H ₂
Correct answer
A. C ₆ H ₅ + C HC ₆ H ₅
Step-by-step solution
C ₆ H ₅ + C HC ₆ H ₅ is the most stable, since the positive charges can be delocalised over both of phenyl rings.
