Q. $CaOCl_{2}\ + \ H_{2}O\ \rightarrow \ Ca(OH)_{2}\ + \ X$ $X\ + \ CH_{3}CHO\ \rightarrow \ Y$ $Y\ + \ Ca(OH)_{2}\ \rightarrow \ CHCl_{3}.$ What is ‘Y’?
A) $CH_{3}CH(OH)_{2}$
B) $CH_{2}Cl_{2}$
C) $CCl_{3}CHO$
D) $CCl_{3}COCH_{3}$
Explanation
(c)
$CaOCl_{2}\ + \ H_{2}O\ \rightarrow \ Ca(OH)_{2}\ + \ \ Cl_{2}$
(X)
$CH_{3}CHO\ \ + \ \ Cl_{2}\ \ \rightarrow \ \ CCl_{3}CHO$
(X) (Y)
$2CCl_{3}CHO\ + \ Ca(OH)_{2}\ \rightarrow \ 2CHCl_{3}\ + \ (HCOO)_{2}\ Ca$
(Y)
