JEE Advanced Chemistry question

Statement 1: Oxygen is more electronegative than sulphur, yet H2S is acidic, while H2O is neutral Statement 2: H-S bond is weaker than O-H 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

H2S is indeed more acidic than (neutral) H2O, despite oxygen's higher electronegativity — this is because acid strength here is governed primarily by bond dissociation energy rather than electronegativity: the
