Compound A (molecular formula `C_(3)H_(8)O`) is trated with acidified potassium dichromate to form a product B (molecular formula `C_(3)H_(6)O`). B form a shining silver mirror on warming with ammonical silver nitrate. B when treted with an aqueous solution of `H_(2)NCONHNH_(2).HCl` and sodium acetate gives a productC. Identify the structure of CA. `CH_(3)CH_(2)CH = NNNHCONH_(2)`B. `CH_(3)-underset(CH_(3))underset(|)(C ) = NNHCONH_(2)`C. `C_(3)H_(4)O`D. `C_(4)H_(8)O` |

Answer» Correct Answer - A `underset((A))(C_(3)H_(8)O )overset(K_(2)Cr_(2)O_(7)H^(+))rarrunderset((B))(C_(3)H_(6)O)overset(" amm" AgNO_(3))rarr " Silver mirror" overset(H_(2)NCONHNH_(2)HCl)rarr C` Reaction of (B) indicates that it is an aldehyde which thus should be `C_(2)H_(5)CHO` or `CH_(3)CH_(2)CHO` hence C should be `CH_(3)CH_(2)CH = "NNHCONH"_(2)` |
