323003 Assertion :
Primary and secondary alcohols can be distinguished by Victor-Meyer's test.
Reason :
Primary alcohols form nitrolic acid which dissolves in NaOH to form blood red colouration but secondary alcohols fom pseudonitrols which give blue colouration with NaOH.

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.
