P - Block Group 16 Elements - Sulphur - Allotropic Forms

Give reasons Dioxygen is a gas while Sulphur is a solid at room temperature.

Name two allotropes of sulphur.

Assertion: Both rhombic and monoclinic sulphur exist as S₈ but oxygen exists as O₂.

Reason: Oxygen forms pπ – pπ multiple bonds due to small size and small bond length but pπ – pπ bonding is not possible in sulphur.

α and β forms of sulphur are at equilibrium at a temperature known as ______.

Write the electronic configuration of the following elements:

Sulphur (Z = 16)

3.795 g of sulphur is dissolved in 100g of CS₂. This solution boils at 319.81 K. What is the molecular formula of sulphur in solution? The boiling point of CS₂ is 319.45 K. (Given that K_b for CS₂ = 2.42 K kg mol^-1 and atomic mass of S = 32)

Draw structure of sulphur molecule (Rhombic sulphur). Mention bond angle and bond length.

The atomicity of sulphur in orthorhombic sulphur is______________ .

(a) 8                                

(b) 6                                 

(c)  4                                

(d)  2
