Question

Two substances both exhibit hydrogen bonding Substance A has a boiling point of 78.4°C. Substance B has a boiling point of

100°C. Which statement correctly compares the substances? (1 point)
O Substance A has stronger bonds, and it takes less energy to undergo a phase change.
O Substance B has stronger bonds, and it takes less energy to undergo a phase change.
O Substance B has stronger bonds, and it takes more energy to undergo a phase change.
O Substance A has stronger bonds, and it takes more energy to undergo a phase change.

Answer 1

Answer: Substance B has stronger bonds, and it takes more energy to undergo a phase change.

Step-by-step explanation:

Substances with higher boilings have stronger intermolecular forces, and thus require more energy for phase changes to occur.
