What is sulfonation of benzene?

What is sulfonation of benzene?

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.

What is sulfonation reaction?

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 is the rate determining step in sulphonation of benzene?

Formation of arrenium ion is the rate determining step of sullhonation of benzene.

What is sulfonation of aromatic compounds?

Aromatic sulfonation is an organic reaction in which a hydrogen atom on an arene is replaced by a sulfonic acid functional group in an electrophilic aromatic substitution. Aryl sulfonic acids are used as detergents, dye, and drugs.

What is sulfonation in organic chemistry?

Sulfonation: A chemical reaction which introduces the sulfonic acid functional group (-SO3H) into a molecule. Sulfonation with sulfur trioxide and sulfuric acid converts benzene into benzene sulfonic acid.

What is sulphonation example?

Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid. The reaction is reversed by adding hot aqueous acid to benzenesulfonic acid to produce benzene.

What is the meaning of sulfonation?

Definition of sulfonate (Entry 2 of 2) transitive verb. : to introduce the SO3H group into broadly : to treat (an organic substance) with sulfuric acid.

When benzene undergoes a sulfonation reaction the product is?

Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid.

What is electrophile in sulphonation of benzene?

So, the active electrophile in sulphonation of benzene is sulphur trioxide.

What do you mean by the term sulphonation?

Sulphonation Reaction The replacement of the hydrogen atom of an organic compound with sulfonic acid (-SO3H) functional group, often by the reaction with sulfuric acid at higher temperatures, is called Sulphonation. “The introduction of a sulfonic acid group into an aromatic compound is referred to as sulphonation.”

What is meant by term sulphonation?

Sulfonation definition (chemistry) The replacement of a hydrogen atom of an organic compound with a sulfonic acid (-SO3H) functional group, often by reaction with sulfuric acid at high temperatures. noun.

What is sulphonation Class 11?

Hint:When a sulphur group is introduced in a benzene ring that process is called sulphonation. It occurs when benzene is heated with fuming sulphuric acid or concentrated sulphuric acid as a product it yields benzene sulphonic acid. It is followed by electrophilic substitution reaction.

Which type of reaction is sulphonation?

reversible reaction
Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid. The reaction is reversed by adding hot aqueous acid to benzenesulfonic acid to produce benzene.

Which is act as a electrophile in sulfonation reaction?

Sulfur trioxide is an electrophile because it is a highly polar molecule with a fair amount of positive charge on the sulfur atom. It is this which is attracted to the ring electrons.

What is sulphonation reaction Class 11?

Sulphonation of benzene is a process of heating benzene with fuming sulphuric acid (H 2SO 4 +SO 3) to produce benzenesulphonic acid. The reaction is reversible in nature.

Which of the following will undergo sulphonation at fastest rate?

From the above statements, we can conclude that toluene very easily undergoes sulfonation reactions compared to all other compounds given in the options. So, the correct answer is “Option C”.

What is the electrophile in sulfonation of benzene?

sulfur trioxide
Nitration and sulfonation of benzene are two examples of electrophilic aromatic substitution. The nitronium ion (NO2+) and sulfur trioxide (SO3) are the electrophiles and individually react with benzene to give nitrobenzene and benzenesulfonic acid respectively.

Which of the following is most reactive towards Sulphonation?

Q. The most reactive among the following towards sulphonation is

• Toluene. 23%
• Chlorobenzene. 11%
• Nitrobenzene. 13%
• m-Xylene. 53%

Which compound will readily undergo sulfonation?

Toluene is most readily sulphonated among these because methyl group is electron donating (+ I effect), activate benzene ring for electrophilic aromatic substitution.
