What does sulfonic acid react with?
Table of Contents
Sulfonic acids are known to react with solid sodium chloride (salt) to form the sodium sulfonate and hydrogen chloride.
Does benzene react with Sulphuric acid?

Sulfonation of benzene is a process of heating benzene with fuming sulphuric acid (H2SO4 +SO3) to produce benzenesulfonic acid. The reaction is reversible in nature.
How is benzene sulphonic acid formed?
Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid. It is important to note that the chemical formula of the sulfonic group is -SO3H. The reaction is reversed by adding hot aqueous acid to benzenesulfonic acid to produce benzene.
What happens when benzene sulphonic acid reacts with sodium hydroxide?
Solution. Sodium benzene sulphonate reacts with NaOH and then on acidic hydrolysis, it gives phenol. Explanation: Sodium benzene sulphonate reacts with NaOH and then on acidic hydrolysis, it gives phenol.

Is sulfonic acid activating or deactivating?
Carbonyls, sulfonic acids and nitro Thus, these groups make the aromatic ring very electron-poor (δ+) relative to benzene and, therefore, they strongly deactivate the ring (i.e. reactions proceed much slower in rings bearing these groups compared to those reactions in benzene.)
What type of reaction are shown by benzene?
Electrophilic Substitution reaction is a characteristic of an aromatic compound. Hence option (D) is correct. Was this answer helpful?
Does benzene react with bromine?
Benzene reacts with chlorine or bromine in the presence of a catalyst, replacing one of the hydrogen atoms on the ring by a chlorine or bromine atom. The reactions happen at room temperature. The catalyst is either aluminum chloride (or aluminum bromide if you are reacting benzene with bromine) or iron.
What is the reaction involved in preparation of phenol from benzene sulphonic acid?
In this process, benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt is mixed with solid sodium hydroxide and fused at a high temperature. The product of this reaction is sodium phenoxide, which is acidified with aqueous acid to yield phenol.
