Show Answer

Answer:

Correct Answer: D

Solution:

$ CaOCl_2+H_2O\to Ca{{(OH)}_2}+Cl_2 $

$ \underset{\text{2-propanol}}{\mathop{CH_3-\underset{\underset{OH}{\mathop{|}}}{\mathop{CH}}-CH_3+Cl_2}}\to $

$ CH_3-\underset{\underset{O}{\mathop{||}}}{\mathop{C}}-CH_3+2HCl $

$ CH_3-\underset{\underset{O}{\mathop{||}}}{\mathop{C}}-CH_3+3Cl_2\to CCl_3-CO-CH_3+3HCl $

$ \begin{matrix} CCl_3COCH_3 \\ CCl_3COCH_3 \\ \end{matrix}+Ca<\begin{matrix} OH \\ OH \\ \end{matrix}\to 2CHCl_3+\begin{matrix} CH_3COO \\ CH_3COO \\ \end{matrix}>Ca $
