Assertion :Alkenes undergo electrophilic addition whereas aldehydes and ketones undergo nucleophilic addition. Reason: In alkenes the double bond joins two carbon atoms and there is no resultant polarity. In carbonyl compounds, the carbonyl group is highly polar and the high partial positive charge on the C atom makes it subsceptible to nucleophilic attack.

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Alkenes undergo electrophilic addition whereas aldehydes and ketones undergo nucleophilic addition because in alkenes the double bond joins two carbon atoms and there is no resultant polarity. In carbonyl compounds, the carbonyl group is highly polar and the high partial positive charge on the C atom makes it susceptible to nucleophilic attack.
So answer is A.
