Consider the given reaction,the product $'X'$ is:

The product $(A)$ of the following reaction is (bromination does not occur in the benzene ring):

The product $(B)$ in the above reaction is:

Which of the following can decolorize aldehydes and ketones?

Schiff's reagent is

An organic compound $(X)$ with molecular formula $C_3H_6O$ is not readily oxidised. On reduction it gives $(C_3H_8O)$ $(Y)$ which reacts with $HBr$ to give a bromide $(Z)$ which is converted to a Grignard reagent. This Grignard reagent on reaction with $(X)$ followed by hydrolysis gives $2,3-$dimethylbutan$-2-$ol. Compounds $(X)$,$(Y)$ and $(Z)$ respectively are $:$
