Question

Among the following, which has highest boiling point?

• A. Ethyl alcohol
• B. Dimethyl ether
• C. Acetone
• D. Chloroform

Answer 1

The correct option is A Ethyl alcohol

The boiling point of a substance depends on the intermolecular forces of interaction such as van der Waal forces, dipole-dipole, ion-dipole, H-bonding etc.

Higher is the magnitude of attraction among molecules more will be the boiling point.

Since among the given options, alcohols have dipolar interaction and can for intermolecular H-bonds. therefore will have the highest boiling point.

Hence, $A$ is correct.
