Which halogen is known to cause the reaction given below? \(2 \mathrm{Cu}^{2+}+4 \mathrm{X}^{-} \rightarrow \mathrm{Cu}_{2} \mathrm{X}_{2(s)}+\mathrm{X}_{2}\)
1 Only chlorine
2 Only bromine
3 Only iodine
4 All halogens
Explanation:
The product \({{\rm{X}}_2}\) is molecular iodine \(\left( {{{\rm{I}}_2}} \right)\) where X represents an iodide ion \(\mathrm{I}^{-}\). \(2 \mathrm{Cu}^{2+}+4 \mathrm{I}^{-} \rightarrow \mathrm{Cu}_{2} \mathrm{I}_{2}+\mathrm{I}_{2}\)

Which one of the following is the true covalent oxide of iodine?
1 \(\mathrm{I}_{2} \mathrm{O}_{4}\)
2 \(\mathrm{I}_{2} \mathrm{O}_{5}\)
3 \(\mathrm{I}_{2} \mathrm{O}_{7}\)
4 \(\mathrm{I}_{2} \mathrm{O}_{9}\)
Explanation:
In general, higher the oxidation state, more is the covalent character of the oxide. \(\mathrm{I}_{2} \mathrm{O}_{7}\) and \(\mathrm{I}_{2} \mathrm{O}_{9}\) do not exist. \(\mathrm{I}_{2} \mathrm{O}_{4}\) is ionic in nature. It is infact iodyl iodates \([\mathrm{IO}]^{+}\left[\mathrm{IO}_{3}\right]^{-}\). The only covalent oxide of iodine is \(\mathrm{I}_{2} \mathrm{O}_{5}\).

Shape of \(\mathrm{ClO}_{2}^{-}\)ion is
1 linear
2 angular
3 pyramidal
4 tetrahedral
Explanation:
\(\mathrm{ClO}_{2}^{-}\)has two lone pairs and two bond pairs on central atom. Hence shape is angular

Number of sigma and pi bonds in \(\mathrm{ClO}_{2}^{-}\)ion is
1 \(2 \sigma\) and \(2 \pi\)
2 \(2 \sigma\) and \(1 \pi\)
3 \(1 \sigma\) and \(2 \pi\)
4 \(3 \sigma\) and \(2 \pi\)
Explanation:
\(\mathrm{ClO}_{2}^{-}\)has one single bond and one double bond. Hence \(2 \sigma\) bonds and \(1 \pi\) bond.
