Water and Heavy water

Question

In the following reactions which is deuterolysis
I) AlCl₃ + 3D₂O → Al(OD)₃ + 3DCl
II) CaC₂ + 2D₂O → Ca(OD)₂ + C₂D₂
III) Mg₃P₂ + 6D₂O → 3Mg(OD)₂+ 2PD₃

Easy

A

I and II only
B

II and III only
C

I and III only
D

I, II and III

Solution

Deuterolysis means addition of Deuterated water to a compound in the form of D⁺ & OD^- . During Deuterolysis cleavage of bonds in the compound takes place

AlCl₃ + 3D₂O→ A(OD)₃ + 3DCl

CaC₂ + 2D₂O → Ca(OD)₂ + C₂D₂

Mg₃p₂ + 6D₂O→ Ca(OD)₂ + 2pD₃
$\begin{array}{*{20}{c}} {3M{g^{ + 2}}}&{2{p^{ - 3}}} \\ {6O{D^ - }}&{6{D^ - }} \end{array}$
