Question

Assertion (A): Esterification is a process in which a sweet smelling substance is produced.

Reason (R): When esters react with Sodium hydroxide, an alcohol and Sodium salt of Carboxylic acid are obtained.

• A. Both A and R are true and R is correct explanation of the Assertion
• B. Both A and R are true but R is not the correct explanation of the Assertion
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is B

Both A and R are true but R is not the correct explanation of the Assertion

Explanation for the correct answer:-

Option (B) Both A and R are true but R is not the correct explanation of the Assertion

• Esterification reaction is a type of reaction where an alcohol and carboxylic acid react with each other and a sweet smell compound of ester is formed.
• The complete reaction is:

• So the Assertion is true.
• When an ester reacts with Sodium hydroxide the products formed are alcohol and carboxylic acid.
• This process is known as Hydrolysis of ester.
• Also this alkaline hydrolysis of ester is called Saponification.
• The complete reaction is:

• Thus both the assertion and reason are true but the reason is not correct explanation for the assertion.
• Hence is the correct option.

Therefore, option (B) is the correct answer.
