A) \[{{D}_{2}}O\] freezes at lower temperature than \[{{H}_{2}}O\]
B) Reaction between \[{{H}_{2}}\] and \[C{{l}_{2}}\] is much faster than \[{{D}_{2}}\]and \[C{{l}_{2}}\]
C) Ordinary water gets electrolysed more rapidly than \[{{D}_{2}}O\]
D) Bond dissociation energy of \[{{D}_{2}}\] is greater than \[{{H}_{2}}\]
Correct Answer: A
Solution :
[a] \[{{D}_{2}}O\]actually has higher freezing point \[\left( 3.8{}^\circ C \right)\] than water \[{{H}_{2}}O\left( 0{}^\circ C \right)\]
