Q. Least stable oxide of chlorine is
A) Cl_{2}O
B) ClO_{2}
C) Cl_{2}O_{7}
D) ClO_{3}
Explanation
(a)
The stability of oxides increases with increase in oxidation state of halogen.
[table] Oxide oxidation state of halogen ; Cl_{2}O +1
ClO_{2} +4
ClO_{3} +6
Cl_{2}O_{7} +7 [/table]
$\therefore\$Cl_{2}O is least stable oxide of chlorine.
