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:

TestHub · Accepted Answer

Assertion is incorrect since in hydrogen bonding, Dipole-dipole interactions are noncovalent but ion-dipole interaction can also result in $H$ -bond formation.

Reason is correct since $F$ is most electronegative element & structure is

Symmetrical $H$ -bonds are present
