07. The p-BLOCK ELEMENTS (XII)

189228 Point out in which of the following properties oxygen differs from the rest of the members of its family (Group - $V I - A$ )

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)

189229 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

2 S O_{2} + O_{2} \to 2 S O_{3}

3

S O_{2} + H_{2} O \to H_{2} S O_{4}

4

N_{2} + 3 H_{2} \to 2 N H_{3}

Explanation:

In the preparation of sulphuric acid, $V_{2} O_{5}$ is used in the reaction of absorption of $O_{2}$ in $S O_{2}$ .
$2 S O_{2} + O_{2} \overset{V_{2} O_{5}}{⟶} 2 S O_{3}$

07. The p-BLOCK ELEMENTS (XII)

189239 Which of the following bonds has the highest energy

1

S e - S e

2

T e - T e

3

S - S

4

O - O

Explanation:

Due to lower size and less electron-electron repulsion, $S - S$ have highest bond energy.

1 Marshell's acid

2 Caro's acid

3 Sulphuric acid

4 None of these

Explanation:

(b) Caro’s acid ( $H_{2}$ $S O_{2}$ )

4

N_{2} + 3 H_{2} \to 2 N H_{3}

Explanation:

In the preparation of sulphuric acid, $V_{2} O_{5}$ is used in the reaction of absorption of $O_{2}$ in $S O_{2}$ .
$2 S O_{2} + O_{2} \overset{V_{2} O_{5}}{⟶} 2 S O_{3}$
