Which of the following is a polar protic solvent? Chloroform Methanol Acetone Acetonitrile Diethyl ether

Methanol

Explanation:

Polar protic solvents -

The solvents that have both the properties, i. e., polarity i. e. dipole moment is non zero and have a proton.

Methanol is the only solvent, which is polar and also have a protons.

while Chloroform is only polar but not protic in nature, as it does not have any hydrogen. Acetonitrile is polar but not protic Acetone is polar but not protic Diethyl ether is neither polar nor is protic in nature.
