On treatment of the following compound with a strong acid, the most susceptible site for bond cleavage is :
Multiple Choice Options
- A Cl O2
- B O2 C3
- C C4 O5
- D O5 C6
Step-by-Step Verified Solution
Here the lone pair of electrons on O2 is involved in resonace with C = C.
So, O2 will not be protonated.
The lone pair electrons of O5 is not involved in resonance with any C = C. So, O5 can be protonated.
When we use strong acid like HCl then chloride ion will attack least substituted C atom (C6).
So, O2 will not be protonated.
