Assertion :Ketones are less electrophilic than aldehydes. Reason: The positive inductive effect of the second alkyl radical reinforces that of the first one decreasing still further the partial positive charge on the carbonyl carbon atom.This reduces the attraction of the atom for nucleophilic reagents. Hence ketones are less electrophilic.
a. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
b. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
c. Assertion is correct but Reason is incorrect
d. Both Assertion and Reason are incorrect
