For question numbers 13 and 14, two statements are given – one labelled as Assertion (A) and the other labelled as Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below :
Assertion (A): Ethanoic acid is also known as glacial acetic acid.
Reason (R): The melting point of pure ethanoic acid is 290 K and hence it often freezes during winters in cold climates.
- (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.
