Assertion : Primary and secondary alcohols can be distinguished by Victor-Meyer's test. Reason : Primary alcohols form nitrolic acid which dissolves in to form blood red colouration but secondary alcohols fom pseudonitrols which give blue colouration with .
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
a) b) c) Primary, Secondary and Tertiary alcohols can be distinguished by Victor Meyer's method. Primary alcohol gives red colour, secondary gives blue colour and tertiary alcohol has no reaction. So the option (1) is correct.
