MCQ
Two statements are given $-$ one labelled Assertion $(A)$ and the other labelled Reason $(R)$. Select the correct answer to these questions from the codes $\ce{(a), (b), (c)}$ and $(d)$ as given below :
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.
  • ✓
    Both $A$ and $R$ are true but $R$ is not the correct explanation of the Assertion.

✓

Answer

Correct option: B.
Both $A$ and $R$ are true but $R$ is not the correct explanation of the Assertion.
When alcohol is added to carboxylic acid with sodium hydroxide and heated in bath tub, it produces a sweet smell of ester and this process is called Esterification.
