CHXI11:THE P-BLOCK ELEMENTS

316614 Volatile nature of halogens is because

1 Halogen molecules are bonded by strong forces

2 Halogen molecules are bonded by electrostatic forces

3 The forces existing between the discrete molecule are only weak Van der Waal's forces

4 Halogen molecules are more reactive

CHXI11:THE P-BLOCK ELEMENTS

316615 Which from the following elements of halogen family is in liquid state at room temperature?

1 Iodine

2 Astatine

3 Bromine

4 Fluorine

CHXI11:THE P-BLOCK ELEMENTS

316616 The Vander waals forces in halogens increase in the order

1

F_{2} < {Cl}_{2} < {Br}_{2} < I_{2}

2

I_{2} > {Br}_{2} > F_{2} > {Cl}_{2}

3

F_{2} < {Br}_{2} < I_{2} < {Cl}_{2}

4

{Br}_{2} < F_{2} < {Cl}_{2} < I_{2}

Explanation:

Vander Waal's forces increases $F_{2}$ from to $I_{2}$ as these forces are directly proportional to molecular masses.

316617 The halogen which is solid at room temperature is

1

I_{2}

2

{Br}_{2}

3

{Cl}_{2}

4

F_{2}

CHXI11:THE P-BLOCK ELEMENTS

316618 Assertion :
All the halogens are coloured.
Reason :
Halogen molecules absorb some wavelengths of visible light and the electrons are promoted to higher energy molecular orbitals.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.

3 Assertion is correct but Reason is incorrect.
