1.	An organic compound (A) of molecular formula C_3H_6Oreduces Tollen's reagent on reaction with methyl magnesium bromide followed by acid hydrolysis gives (B) of formula C_4H_10 O(B) gives blue colour in victor meyer test. (B) on reaction with Cu at 573 K gives (C) of formula C_4H_8O(C) on reaction with hydrazine and sodium ethoxide gives (D) of 'molecular formula C_4H_10. Identify A,B,C,D and explain the reactions involved.
Answer» Solution :(i) An ORGANIC compound (A) reduces Tollen.s reagent it must be an aldehyde. From the formula, it is identified as `CH_2 - CH_2 - CHO` propanal. (ii) Propanal on reaction with methyl magnesium bromide followed by acid hydrolysis gives (B) as BUTAN - 2 - ol. It must be a SECONDARY alcohol and gives blue colour with victor meyer.s test.
