Assertion (A): is more reactive for electrophilic addition reaction than
Reason (R): Carbocation intermediate formed in alkene is more stable than the alkyne.
Reason (R): Carbocation intermediate formed in alkene is more stable than the alkyne.
View answer and explanation
Correct option: D
Both A R are incorrect
Option D is correct because alkynes are generally less reactive than alkenes towards electrophilic addition due to the sp hybridization of the carbon atoms in the triple bond, which makes them more electronegative and less likely to donate electrons. Also, the carbocation formed in alkene is more stable than the vinyl carbocation formed in alkyne.
