For question numbers 13 and 14, two statements are given – one labeled as Assertion (A) and the other labeled 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.(c) (A) is true but (R) is false.(d) (A) is false but (R) is true.
Correct Answer: (a) Both (A) and (R) are true and (R) is correct explanation of the assertion.
Explanation: Ethanoic acid is also known as glacial acetic acid. The melting point of pure ethanoic acid is 290 K and hence it often freezes during winters in cold climates.
