An 'Assertion' and a 'Reason' are given below. Choose the correct answer from the following options :
Assertion (A) : Vinyl halides do not undergo nucleophilic substitution easily.
Reason (R) : Even though the intermediate carbocation is stabilized by loosely held p-electrons, the cleavage is difficult because of strong bonding.
Assertion (A) : Vinyl halides do not undergo nucleophilic substitution easily.
Reason (R) : Even though the intermediate carbocation is stabilized by loosely held p-electrons, the cleavage is difficult because of strong bonding.
Multiple Choice Options
- A Both (A) and (R) are correct statements but (R) is not the correct explanation of (A)
- B Both (A) and (R) are correct statements and (R) is the correct explanation of (A)
- C (A) is correct statement but (R) is a wrong statement
- D Both (A) and (R) are wrong statements.
Step-by-Step Verified Solution
Due to resonance C - Cl bond strength increses, that is why C - Cl bond do not break easily and don't show nucleophilic substitution reaction easily.
