CHXI11:THE P-BLOCK ELEMENTS

316238 Choose the correct statements from the following.
(I) All group 16 elements form oxides of general formula \({\mathrm{\mathrm{EO}_{2}}}\) and \({\mathrm{\mathrm{EO}_{3}}}\), where \({\mathrm{\mathrm{E}=\mathrm{S}, \mathrm{Se}, \mathrm{Te}}}\) and Po. Both the types of oxides are acidic in nature.
(II) \({\mathrm{\mathrm{TeO}_{2}}}\) is an oxidising agent while \({\mathrm{\mathrm{SO}_{2}}}\) is reducing in nature.
(III) The reducing property decreases from \({\mathrm{\mathrm{H}_{2} \mathrm{~S}}}\) to \({\mathrm{\mathrm{H}_{2} \mathrm{Te}}}\) down the group.
(IV) The ozone molecule contains five lone pairs of electrons.
Choose the correct answer from the options given below:

1 (III) and (IV) only
2 (I) and (IV) only
3 (I) and (II) only
4 (II) and (III) only

316239 \(\mathrm{SF}_{6}\) is known but \(\mathrm{SCl}_{6}\) is not. Why?

1 Due to small size of fluorine
2 Due to high electronegativity of fluorine
3 Due to high electron affinity of chlorine
4 Due to less electronegativity of chlorine
CHXI11:THE P-BLOCK ELEMENTS

316240 Assertion :
\(\mathrm{SF}_{6}\) cannot be hydrolysed but \(\mathrm{SF}_{4}\) can be.
Reason :
Six \(\mathrm{F}\) atoms in \(\mathrm{SF}_{6}\) prevent the attack of \(\mathrm{H}_{2} \mathrm{O}\) on sulphur atom of \(\mathrm{SF}_{6}\).

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.
4 Assertion is incorrect but Reason is correct.
