Predict which member of each pair has the higher boiling

Solution 34SP:

Here, we are going to predict which member of each pair has the higher boiling point, with reason.

Boiling point of alcohol depends on the following factors.

1. Molecular weight
2. Hydrogen bonding
3. Dipole-dipole attraction

(a) hexan-1-ol or 3,3-dimethylbutan-1-ol

Step 1: The structure of the compounds are as follows:

Here, hexan-1-ol has the higher boiling point than 3,3-dimethylbutan-1-ol. This is because, hexan-1-ol is less branched than 3,3-dimethylbutan-1-ol.

(b) hexan-2-one or hexan-2-ol
