Question

multiple choice 2 points which of the following has the highest boiling point?

Explanation:

Step1: Consider intermolecular forces

The strength of intermolecular forces affects boiling - point. Compounds with hydrogen - bonding have higher boiling points than those with only dipole - dipole or London dispersion forces.

Step2: Analyze each compound

The first compound has a chlorine atom, so it has dipole - dipole forces. The second compound is an alkene and has only London dispersion forces. The third compound has an -OH group, which can form hydrogen bonds. The fourth compound is an ether and has dipole - dipole forces.

Step3: Compare boiling points

Hydrogen bonds are the strongest of these intermolecular forces. So, the compound with the -OH group has the highest boiling point among them.

Answer:

The compound with the -OH group (the third - option with the OH functional - group)
