Answer» Solution :The PRODUCTS A, B, C, D are identified with the help of the following reactions : (i)`CH_(3)CH_(2)OH overset(K_(2)Cr_(2)O_(7))UNDERSET(H(2)SO_(4)) to CH_(3)COOH overset(SOCl_(2))to CH_(3)COCl overset(NH_(3))to CH_(3)CONH_(2) overset(NaOBr)to CH_(3)NH_(2)` (ii) `CH_(3)CH_(2)CL overset(KCN) to underset(A)(CH_3)CH_(2)C-= N overset(OH^(-))underset(H_(2)O_(2)) to CH_(3)CH_(2) - underset(B)overset(O)overset(|\)C-NH_(2) overset(P_(2)O_(3))underset("Dehydration")to underset( C)(CH_(3)CH_(2)C -= N + H_(2)O)` (iii) `CH_(3)COOH overset(C_(2)H_(5)OH)underset("conc "H_(2)SO_(4)) to underset(A)(CH_(3)COOC_(2)H_(5)) overset(CH_(3)MgBr)underset(H_(2)O//H^(+)) to CH_(3) -underset(B)overset(O)overset(||)C-CH_(3) overset(CH_(3)MgBr)underset(H_(2)O//H^(+)) to CH_(3) - underset(CH_(3))underset(|)overset(OH)overset(|)C-CH_(3)` |
