Write the structures of the main products when CH_(3) CH_(2) CHO reacts with the following : (a) Zn - Hg // conc. HCl(b) H_(2) N- NH_(2) //H^(+)(c ) HCN

Answer»

Solution :(a) `CH_(3) CH_(2) CHO underset( "CLEMMENSEN reduction")overset(Zn-Hg//"conc. HCL")(rarr) underset("Propane")(CH_(3)CH_(2)CH_(3))`
(b) `CH_(3) H_(2) CHO overset( NH_(2) OH // H^(+))(rarr) underset( "Propanal OXIME")(CH_(3) CH_(2) CH = NOH)+ H_(2) O`
(c ) `CH_(3) CH_(2) CHO + HCN rarr underset( "Propanal cyanohydrin")(CH_(3) CH_(2) - underset( CN)underset( |) overset( H ) overset( |)(C ) - OH)`
