II. Read the passage given below and answer the following questions :
Oxidation of alcohols incolves the formation of a carbon - oxygen double bond with cleavage of an O-H and C-H bonds.

Such a cleavage and formation of bonds occur in oxidation reaction. These are also known as dehydrogenation reactions as these involve loss of dihydrogen from an alcohol molecule. Depending on the oxidising agent used, a primary alcohols is oxidised to an aldehyde which in tuen is oxidised to a carboxylic acid.
Strong oxidising agents such as acidified potassium permanganate are used for getting carboxylic acids from alcohols directly. `CrO_(3)` in anhydrous medium is used as the oxidising agent for the isolation of aldehydes.
Assertion (A) : Vapours of primary and secondary alcohols are passed through heated copper an aldehyde and ketone are formed.
Reason (R ) : It's a dehydration reaction.

Options

A. Assertion and reason both are correct statements and reason is correct explanation for assertion.
B. Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C. Assertion is correct statement but reason is wrong statement.
D. Assertion is wrong statement but reason is correct statemets

Answer

C

Explanation

Vapours of primary and secondary alcohols are passed through heated copper an aldehyde and ketone are formed. It.s a dehydrogenation reaction.
