Front

What happens to the solubility of carboxylic acids as their size increases?

Back

The solubility decreases as the size of carboxylic acids increases.

Front

How do the melting and boiling points of carboxylic acids change with size?

Back

As carboxylic acids increase in size, their melting and boiling points increase due to the increasing strength of the intermolecular forces.
