Two substances both exhibit hydrogen bonding. Substance A has a boiling point of 78.4ºC. Substance B has a boiling point of 100ºC. Which statement correctly compares the substances?(1 point)
Substance A has stronger bonds, and it takes more energy to undergo a phase change.
Substance B has stronger bonds, and it takes less energy to undergo a phase change.
Substance A has stronger bonds, and it takes less energy to undergo a phase change.
Substance B has stronger bonds, and it takes more energy to undergo a phase change
Its D, Just took test
The correct statement is:
Substance B has stronger bonds, and it takes more energy to undergo a phase change.
To compare the substances and determine which one has stronger bonds, we can look at their boiling points. Boiling point is a measure of the strength of intermolecular forces between molecules. Substances with stronger intermolecular forces require more energy to overcome these forces and undergo a phase change from a liquid to a gas.
In this case, Substance B has a higher boiling point of 100ºC, compared to Substance A with a boiling point of 78.4ºC. This indicates that Substance B has stronger intermolecular forces, specifically hydrogen bonding, which requires more energy to break and transition into a gas phase.
Therefore, the correct statement is: Substance B has stronger bonds, and it takes more energy to undergo a phase change.
