Vedclass · Answer

(A) Since product '$Y$' gives a silver mirror test,it must be an aldehyde. '$Y$' is formed by the oxidation of '$X$',which indicates that '$X$' is a primary alcohol $(CH_3CH_2CH_2OH)$.$CH_3CH_2CH_2OH (X) \xrightarrow{K_2Cr_2O_7 + H_2SO_4} CH_3CH_2CHO (Y)$When '$Y$' $(CH_3CH_2CHO)$ reacts with semicarbazide $(NH_2CONHNH_2)$ in the presence of sodium acetate,it forms a semicarbazone derivative.$CH_3CH_2CHO + NH_2CONHNH_2 \rightarrow CH_3CH_2CH=NNHCONH_2 + H_2O$The product '$Z$' is $CH_3CH_2CH=NNHCONH_2$.

Compound '$X$' (molecular formula $C_3H_8O$) reacts with acidic potassium dichromate to give product '$Y$' (molecular formula $C_3H_6O$). '$Y$' gives a silver mirror test. When '$Y$' is reacted with aqueous $NH_2CONHNH_2$ and sodium acetate,it gives product '$Z$'. What is the structure of '$Z$'?
