The magnitude of hydrogen bonding in a compound is:
APresent only in the liquid state
BMaximum in the gaseous state and minimum in the solid state
CMaximum in the solid state and minimum in the gaseous state
DEqual in all three states
Answer & Solution
Correct answer: C. Maximum in the solid state and minimum in the gaseous state
H-bonding strength is **maximum in the solid state** (fixed, optimal geometry) and minimum in the gaseous state (molecules far apart). This is why ice has anomalously low density and high melting point.
