**Statement 1:** In aqueous HF solution, H_3O^+ and F^- ions are found. **Statement 2:** Hydrogen bonding in HF is stronger than that in H_2O.

JEE Main Chemistry question

**Statement 1:** In aqueous HF solution, and ions are found. **Statement 2:** Hydrogen bonding in HF is stronger than that in .

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

Answer: (B)

Solution

HF does partially ionise in water to give and (it is a weak acid), so the assertion is true, and the H–F hydrogen bond is indeed one of the strongest known (stronger than in water), so the reason is also true.
