Question

Statement-1 : Boiling point of `H_(2)O` is more than HF .
and
Statement-2 : Intermolecular hydrogen bonding in HF is stronger than `H_(2)O`.
A. H - F has highest van der Waals forces and dipole moment.
B. H - F has highest London forces.
C. H - F has highest dipole moment hence has dipole - dipole , London forces and hydrogen bonding.
D. H - F has strong intermolecular interactions like dipole - induced dipole.

Answer 1

Correct Answer - C
H-F has dipole-dipole interaction, London forces and hydrogen bonding due to highest electronegativity of F. Hence, boiling point of H-F is highest.
