Q. Compound $(X)$ with molecular formula $C_{3}H_{8}O$ is treated with acidified potassium dichromate to form a product $(Y)$ with molecular formula $C_{3}H_{6}O. (Y)$ does not form a shining silver mirror on warming with ammoniacal $AgNO_{3}. (Y)$ when treated with an aqueous solution of $NH_{2}CONHNH_{2}. HCl$ and sodium acetate, gives a product $(Z)$. The structure of $(Z)$ is
Aldehydes Ketones and Carboxylic Acids
Solution:
Correct answer is (b) $ (CH_{3})_{2}C = NNHCONH_{2}$
