Question

HCI does not act as an acid in benzene because-
A.benzene does not accept protons
B.benzene neutralises HCl
C.both a and b
D.none of these

Answer 1

Hint: The organic chemical compound benzene has the molecular formula ${C_6}{H_6}$. The benzene molecule is made up of six carbon atoms arranged in a planar ring, each containing one hydrogen atom. Benzene is classified as a hydrocarbon because it only has carbon and hydrogen atoms. One of the most basic petrochemicals is benzene, which is a natural component of crude oil. Benzene is classified as an aromatic hydrocarbon because of the cyclic continuous pi bonds between the carbon atoms.

Complete answer:
Many functional groups are added to the benzene framework through electrophilic aromatic substitution. The usage of oleum, a combination of sulfuric acid and sulphur trioxide, is used to sulfonate benzene. Detergents based on sulfonated benzene derivatives are beneficial. When benzene combines with nitronium ions ($N{{O}_{2}}^{+}$), a powerful electrophile formed by mixing sulfuric and nitric acids, nitronium ions are formed. The precursor to aniline is nitrobenzene. In the presence of a Lewis acid catalyst, such as aluminium tri-chloride, chlorine is used to produce chlorobenzene.
But in case of HCl
With HCl, benzene would never react. Because HCl is an inorganic acid, it lacks an electrophile to replace benzene's H atom. Because Cl is a Lewis base, it does not behave as an electrophile. In Benzene, HCl dissolves quickly. Non-aqueous solvents, such as benzene, are one example. When HCl is dissolved in Benzene, it does not behave like an acid. There are no molecules that can take protons in this vicinity.

Hence option a is correct.

Note:
Hydrochloric acid is the monoprotic acid least likely to conduct an interfering oxidation-reduction reaction among the six main strong mineral acids in chemistry. Despite its acidity, it contains the non-reactive and non-toxic chloride ion, making it one of the safest strong acids to handle. Intermediate-strength hydrochloric acid solutions are quite stable when stored, and their concentrations remain constant over time. Hydrochloric acid is an effective acidifying reagent because of these characteristics and the fact that it is available as a pure reagent. It is also reasonably priced.
