An aprotic solvent is a solvent that has no O-H or N-H bonds.

The "a" means "without", and "protic" refers to protons or hydrogen atoms.

The specific meaning of aprotic is that the molecules have no H atoms on O or N.

This means that the molecules cannot form H-bonds with themselves, but they may accept H-bonds from other molecules.

For example, acetone does not have an O-H group, but it has a C=O group that can participate in H-bonding.

So acetone is an aprotic solvent.

Some other common aprotic solvents are listed below.
