Question

Choose the best reaction sequence that could be used to perform the following transformation.

• A. $\underset{AlC{l}_3}{\overset{H_{3}C-C{H}_{2}Cl}{\to }}\stackrel{C{l}^{-}}{\to }$
• B. $\underset{FeC{l}_3}{\overset{C{l}_2}{\to }}\underset{AlC{l}_3}{\overset{H_{3}C-Cl}{\to }}$
• C. $\underset{FeC{l}_3}{\overset{C{l}_2}{\to }}\underset{AlC{l}_3}{\overset{H_{3}C-\stackrel{O}{\stackrel{||}{C}}-Cl}{\to }}\underset{ii.KOH}{\overset{i.N_2{H}_4}{\to }}$
• D. $\underset{AlC{l}_3}{\overset{H_{3}C-\stackrel{O}{\stackrel{||}{C}}-Cl}{\to }}\underset{ii.KOH}{\overset{i.N_2{H}_4}{\to }}\underset{FeC{l}_3}{\overset{C{l}_2}{\to }}$

Answer 1

The correct option is D $\underset{AlC{l}_3}{\overset{H_{3}C-\stackrel{O}{\stackrel{||}{C}}-Cl}{\to }}\underset{ii.KOH}{\overset{i.N_2{H}_4}{\to }}\underset{FeC{l}_3}{\overset{C{l}_2}{\to }}$
