NEET Chemistry Alkynes Assertion Reason Question
Assertion (A): In the electrophilic addition reactions of alkynes, the addition of hydrogen halides occurs according to Markovnikov's rule.
Reason (R): The stability of the vinylic cation determines the addition product in unsymmetrical alkynes.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
Both statements are true. In alkynes, the addition of hydrogen halides follows Markovnikov's rule due to the stability of the vinylic cation formed during the reaction, as mentioned in the NCERT context.
