The aprotic solvent is

Solution (By Examveda Team)

In chemistry, aprotic solvents are solvents that cannot donate hydrogen bonds (protons). They lack an acidic hydrogen atom and thus do not participate in hydrogen bonding. Aprotic solvents are often used in reactions where proton transfer is not desired.

Among the options provided:
H₂O (Option A) is a protic solvent as it can donate hydrogen bonds.
HF (Option C) is also a protic solvent as it contains hydrogen atoms bonded to fluorine, which can participate in hydrogen bonding.
NH₃ (Option D) is a protic solvent as it can donate a hydrogen atom in solution.

However, C₆H₆ (Option B), which is benzene, is an example of an aprotic solvent. It lacks hydrogen atoms that are capable of forming hydrogen bonds.

Therefore, Option B: C₆H₆ is the correct choice for an aprotic solvent.
