Question

Can you provide a simple diagram that would explain (why/how)the difference in boiling temperature between an alcohol and a diol?

Answer 1

Step-by-step explanation:

Hydrogen bonding, present in alcohols but not hydrocarbons, leads to strong intermolecular forces and increases the boiling point significantly.

For example:

Glycerol has 3 OH groups, which lead to a much more extensive hydrogen-bonding network and a higher boiling point compared to the 1 OH or 2 OH in other chains.
