**Assertion:** Oxygen is more electronegative than sulphur, yet H_2S is acidic while H_2O is neutral. **Reason:** The H-S bond is weaker than the O-H bond.

JEE Main Chemistry question

**Assertion:** Oxygen is more electronegative than sulphur, yet is acidic while is neutral. **Reason:** The - bond is weaker than the - 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

Despite oxygen's greater electronegativity, acid strength of binary hydrides down a group is governed primarily by bond strength, not electronegativity; the much weaker - bond
