    Assertion (A) Benzaldehyde is less reactive in comparison to ethanol towards nucleophilic attack. Reason (R) All the carbon atoms of benzaldehyde are \[V=\sqrt[3]{v_{0}^{3}+{{\omega }^{3}}{{X}^{3}}}\]hybridised. Each of these questions contains two statements. Assertion (A) and Reason (R). Each of these questions also has four alternative choices, only one of which is the correct answer. You have to select one of the codes (a), (b), (c) and (d) given below.

    A) If both Assertion and Reason are true and Reason is correct explanation of Assertion.

    B) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

    C) If Assertion is true but Reason is false.

    D) If both Assertion and Reason are false.

    Correct Answer: B

    Solution :

    Because of electron donating effect of the benzene ring, the carbonyl carbon of benzaldehyde is less electrophilic.
