Hint: A solvent is a substance that dissolves a solute in it and forms a solution. Solvents are classified into two broad categories: Polar and nonpolar.

Complete answer:
Polar Protic Solvents:
Polar Protic solvents are solvents that can form hydrogen bonds with the substrate. They can form hydrogen bonds because they contain at least one hydrogen atom that is directly connected to an electronegative atom (such as O-H or N-H bonds).
Examples are: Water, ethanol, methanol, ammonia, acetic acid, and other polar protic solvents.
Polar Aprotic Solvents:
Polar Aprotic solvents are those that are unable to form hydrogen bonds with the substrate. They have no hydrogen atoms that are directly connected to an electronegative atom and are not capable of hydrogen bonding.
Examples are: Acetone, Chloroform, Dichloromethane, and other aprotic solvents.

Note:
Aprotic solvents may have hydrogens on them somewhere, but they lack O-H or N-H bonds, and therefore cannot hydrogen bond with themselves.
