Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: Dipole-dipole interactions are the only non-covalent interactions, resulting in hydrogen bond formation. Reason R: Fluorine is the most electronegative element and hydrogen bonds in HF are symmetrical. In the light of the above statements, choose the most appropriate answer from the options given below: – 2

(A) A is true but R is false
(B) Both A and R are true but R is NOT the correct explanation of A
(C) Both A and R are true and R is the correct explanation of A
(D) A is false but R is true

Correct answer: A) A IS TRUE BUT R IS FALSE. Hydrogen bond can also be between an ion and a dipole, for example F with H O. Thus, assertion is incorrect. The statement given in reason is correct.
