Answer: (B) Option
Explanation:
The polar molecule contains bonds between very different electromagnetic atoms, such as oxygen and hydrogen, and have large dipole moments. The non-polar molecule contains bonds between atoms with similar electronegativities, such as carbon and hydrogen. These polar solvents are able to form hydrogen bonds with water to dissolve in water, and non-polar solvents cannot affect hydrogen bonds strongly.
Further Polar molecule are divided into two categories: Polar protic and polar aprotic molecule
Polar protic solvents are capable of hydrogen bonding because they contain at least one hydrogen atom linked directly to an electron (electronegative) atom (such as O-H or N-H bonds). Polar protic solvents are water, ethanol, methanol, ammonia, acetic acid, and others.
On the other hand
Polar aprotic solvents contain a hydrogen atom that is directly connected to an electron(electronegative) atom and cannot able to do hydrogen bonding. These are acetone, dimethyl sulfoxide, DMF (N, N-dimethylformamide), acetonitrile, HMF (hydroxymethylfurfural), crown ethers and others.
Therefore (B) option is polar aprotic solvent
