The chart above shows the boiling points of 3 substances. Based on the boiling point values, which list correctly orders the substances from WEAKEST intermolecular forces (listed first) to STRONGEST intermolecular forces (listed last).
To determine the order of the substances from weakest intermolecular forces to strongest intermolecular forces based on their boiling points, we need to analyze the data given in the chart.
Looking at the chart, we see that Substance C has the lowest boiling point, Substance B has a higher boiling point than Substance C, and Substance A has the highest boiling point among the three substances.
From this data, we can infer that Substance C has the weakest intermolecular forces, Substance B has stronger intermolecular forces than Substance C but weaker than Substance A, and Substance A has the strongest intermolecular forces among the three substances.
Therefore, the correct order from weakest to strongest intermolecular forces is: Substance C, Substance B, Substance A.
a
Methanol, ethanol, water
b
Water, ethanol, methanol
c
Ethanol, methanol, water
d
Ethanol, water, methanol
The correct order from weakest to strongest intermolecular forces based on the boiling points of the substances is:
c) Ethanol, methanol, water
