Point out in which of the following properties oxygen differs from the rest of the members of its family (Group - \(VI-A\))
1 High value of ionisation energies
2 Oxidation states (\(2, 4, 6\))
3 Polymorphism
4 Formation of hydrides
Explanation:
(b) Oxidation states are \(2, 4, 6\)
07. The p-BLOCK ELEMENTS (XII)

In the preparation of sulphuric acid, \({V_2}{O_5}\) is used in the reaction, which is
1 \(S + {O_2} \to S{O_2}\)
2 \(2S{O_2} + {O_2} \to 2S{O_3}\)
3 \(S{O_2} + {H_2}O \to {H_2}S{O_4}\)
4 \({N_2} + 3{H_2} \to 2N{H_3}\)
Explanation:
In the preparation of sulphuric acid, \(V _2 O _5\) is used in the reaction of absorption of \(O _2\) in \(SO _2\). \(2 SO _2+ O _2 \stackrel{ V _2 O _5}{\longrightarrow} 2 SO _3\)
07. The p-BLOCK ELEMENTS (XII)
189239
Which of the following bonds has the highest energy
1 \(Se - Se\)
2 \(Te - Te\)
3 \(S - S\)
4 \(O - O\)
Explanation:
Due to lower size and less electron-electron repulsion, \(S-S\) have highest bond energy.
