Question

Write the structures of A, B and C in the following reactions:

(i) C₆H₅N₂Cl \(\overset{CuCN}{\underset{KCN}{\longrightarrow}}\) A \(\overset{H_2O/H^+}{\longrightarrow}\) B

(ii) CH₃COOH \(\underset{\Delta}{\longrightarrow}\) A \(\overset{NaOBr}{\longrightarrow}\) B \(\overset{NaNO_2/HCl}{\longrightarrow}\)

(iii) CH₃Br \(\overset{KCN}{\longrightarrow}\) A \(\overset{LiAlH_4}{\longrightarrow}\) B \(\overset{HNO_2}{\longrightarrow}\) C

Answer 1

(i) C₆H₅N₂Cl \(\overset{CuCN}{\underset{KCN}{\longrightarrow}}\) A \(\overset{H_2O/H^+}{\longrightarrow}\) B

 (ii) CH₃COOH \(\underset{\Delta}{\longrightarrow}\) A \(\overset{NaOBr}{\longrightarrow}\) B \(\overset{NaNO_2/HCl}{\longrightarrow}\)

(iii) CH₃Br \(\overset{KCN}{\longrightarrow}\) A \(\overset{LiAlH_4}{\longrightarrow}\) B \(\overset{HNO_2}{\longrightarrow}\) C
