FAQs on Cannizzaro Reaction & Electrophilic Substitution Video Lecture - Chemistry for JEE Main & Advanced

1. What is the Cannizzaro reaction?

Ans. The Cannizzaro reaction is a chemical reaction in which an aldehyde molecule undergoes self-disproportionation to form an alcohol and a carboxylic acid. It is a redox reaction that involves the transfer of hydride ions between two aldehyde molecules.

2. What is the mechanism of the Cannizzaro reaction?

Ans. The mechanism of the Cannizzaro reaction involves a nucleophilic attack by a hydroxide ion on one aldehyde molecule, forming a negatively charged alkoxide intermediate. The alkoxide intermediate then undergoes a hydride transfer to another aldehyde molecule, resulting in the formation of an alcohol and a carboxylic acid.

3. What are the conditions required for the Cannizzaro reaction to occur?

Ans. The Cannizzaro reaction typically requires the presence of a strong base, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH), in an aqueous solution. The reaction is often carried out at elevated temperatures to increase the reaction rate.

4. What are the applications of the Cannizzaro reaction?

Ans. The Cannizzaro reaction has several applications in organic synthesis. It can be used to convert aldehydes into their corresponding alcohols and carboxylic acids. It is also utilized in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals.

5. What is electrophilic substitution?

Ans. Electrophilic substitution is a type of organic reaction in which an electrophile replaces a hydrogen atom or a functional group in a molecule. It involves the attack of an electrophile on a nucleophilic site in the molecule, resulting in the formation of a new bond and the substitution of the original group. This process is commonly observed in aromatic compounds, such as benzene, where electrophilic aromatic substitution reactions take place.
