Q.
Given below are two statements:

Statement I: ${SbCl}_{5}$ is more covalent than ${SbCl}_{3}$ .

Statement II: The higher oxides of halogens also tend to be more stable than the lower ones.

In the light of the above statements, choose the most appropriate answer from the options given below: [2023]

1 Statement I is correct but Statement II is incorrect.

2 Statement I is incorrect but Statement II is correct.

3 Both Statement I and Statement II are correct.

4 Both Statement I and Statement II are incorrect.

Ans.
(3)

The halides in higher oxidation state will be more covalent than the one in lower oxidation state. Higher stability of higher oxides is due to greater polarisability and multiple bond formation.

Solution

1 Statement I is correct but Statement II is incorrect.

2 Statement I is incorrect but Statement II is correct.

3 Both Statement I and Statement II are correct.

4 Both Statement I and Statement II are incorrect.

Ans.
(3)

The halides in higher oxidation state will be more covalent than the one in lower oxidation state. Higher stability of higher oxides is due to greater polarisability and multiple bond formation.
