Vedclass · Answer

(A) In the Victor-Meyer's test,the alcohols are converted into nitroalkanes,which are then treated with nitrous acid $(HNO_2)$ and finally made alkaline with $NaOH$.For $1^o$ alcohols,the product is a nitrolic acid,which gives a blood-red colour in alkaline solution.For $2^o$ alcohols,the product is a pseudonitrol,which gives a blue colour in alkaline solution.For $3^o$ alcohols,the product does not react with nitrous acid and remains colourless in alkaline solution.Therefore,the colours are red,blue,and colourless respectively.

In the Victor-Meyer's test,the colours given by $1^o$,$2^o$,and $3^o$ alcohols are respectively:
