Question

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

Answer 1

Methanol is a polar protic solvent among the given options.

A polar protic solvent is a solvent that has a hydrogen atom attached to an electronegative atom and is capable of donating a hydrogen bond.

Based on this definition, the polar protic solvent among the options given is methanol (CH3OH).

Methanol has a hydrogen atom attached to an oxygen atom, which makes it capable of donating a hydrogen bond.

Chloroform, acetone, acetonitrile, and diethyl ether are polar aprotic solvents, meaning they lack an acidic hydrogen atom and cannot donate a hydrogen bond.

Answer 2

Methanol

Step-by-step 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 .
