Assertion : The \(\mathrm{S}-\mathrm{S}-\mathrm{S}\) bond angle in \(\mathrm{S}_{8}\) molecule is \(107^{\circ}\). Reason : \(\mathrm{S}_{8}\) has V - shape.
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 Both Assertion and Reason are incorrect.
Explanation:
\(\mathrm{S}\) - atoms in \(\mathrm{S}_{8}\) molecule are \(\mathrm{sp}^{3}\) hybridised and contain two lone pairs of electrons on each sulphur atom and exist as staggered eight atom ring. Tetrahedral angle is \(109^{\circ}\) but due to lone pairof electrons, it reduces to \(107^{\circ} . \mathrm{S}_{8}\) ring is puckered and has a crown shape, but each ' \(\mathrm{S}\) ' atom is in V-shape only.

4 Assertion is incorrect but Reason is correct.
Explanation:
In a sulfur molecule \(\left( {{{\text{S}}_{\text{8}}}} \right)\), catenation leads to each sulfur atom forming covalent bonds with two neighbours, creating a stable and symmetric octatomic sulfur structure. After forming two bond pairs it remains left with two lone pairs . So 2 bond pair +2 lone pairs \(=4\) orbitals required i.e \(\mathrm{sp}^{3}\). Therefore, option (2) is correct.

Which form of sulphur shows paramagnetic behaviour?
1 Monoclinic sulphur
2 Plastic sulphur
3 Rhombic sulphur
4 \(\mathrm{S}_{2}\) in vapour state
Explanation:
In vapour state sulphur partly exists as \(\mathrm{S}_{2}\) molecule which has two unpaired electrons in the antibonding \(\pi^{*}\) orbitals like \(\mathrm{O}_{2}\) and hence exhibits paramagnetism.
