← ScienceWhich consequence results when liquid ammonia exceeds its critical temperature?
A)Hydrogen bonds are effectively eliminated✓
B)Electronegativity dominates electron distribution
C)Ammonia decomposes producing diatomic nitrogen
D)Ionic character greatly affects conductivity
💡 Explanation
Above the critical temperature, thermal energy disrupts cohesive intermolecular forces; therefore the hydrogen bonding network collapses because the average kinetic energy overwhelms the relatively weak hydrogen bonds, rather than other electronic effects becoming dominant.
