JEE Main Chemistry question

Statement 1: Halogen acids do not add on to carbonyl bond. Statement 2: Addition depends upon the polarization of HX and carbonyl bond.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (A)

Solution

Statement 1 is true: HX acids do not meaningfully add across a C=O bond under ordinary conditions. Statement 2 correctly explains why: in H–X, the halogen (more electronegative) bears the partial negative charge and H the partial positive, which is the "wrong" polarity to interact productively
