The most stable carbonium ion among the following is
Options
- AC ₆ H ₅- CH ₂ + C H ₂
- BCH ₃ + C H ₂
- CC ₆ H ₅- + C - C ₆ H ₅
- DC ₆ H ₅ + C H ₂
Correct answer
C. C ₆ H ₅- + C - C ₆ H ₅
Step-by-step solution
Due to more possibility for delocalisation in C ₆ H ₅- + C - C ₆ H ₅ (of -electrons), C ₆ H ₅- + C - C ₆ H ₅ is the most stable ion.
