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 $
