MCQ
Which of the following chloride does not react with $PCl_5$ on heating?
  • ✓
    $Hg_2Cl_2$
  • B
    $FeCl_2$
  • C
    $S_2Cl_2$
  • D
    $BCl_3$
✓

Answer

Correct option: A.
$Hg_2Cl_2$
a
$8 N H_{3}+3 C l_{2} \rightarrow 6 N H_{4} C l+N_{2}$

(Excess)

$NH _{3}+3 Cl _{2} \rightarrow NCl _{3}+3 HCl$

(Excess)

Hence. $X=6 N H_{4} C l+N_{2}$

$Y=N C l_{3}+3 H C l$
