Question

Which condition increases hydrogen bonding?
Options
A Low electronegativity and large atomic size
B High electronegativity and small atomic size
Correct Answer
C High mass of atoms
D High pressure
Correct Answer

Option B is the correct answer.

Detailed Explanation

Effective hydrogen bonding requires hydrogen to be bonded to a small, highly electronegative atom like N, O, or F. High electronegativity creates a strong dipole, and small size allows the hydrogen to approach closely for a strong attraction.

Hint

What are the characteristics of the atom that hydrogen must be bonded to for hydrogen bonding to occur?
