Question

Pick out the odd property of rhombic sulphur:

1) Rhombic sulphur exists as octahedral crystals.

2) The density of rhombic sulphur is 2.06 g/mL.

3) Rhombic sulphur is a yellow solid with a melting point of 385.8K and is soluble in carbon disulphide and insoluble in water.

Answer 1

Rhombic Sulphur:

• Sulphur is the ${16}^{\mathrm{th}}$ member of the modern periodic table and is a non-metal of Oxygen family.
• Sulphur has two Crystalline allotropes: Rhombic sulphur or alpha $\left(\alpha \right)$ sulphur and Monoclinic sulphur or beta $\left(\beta \right)$ sulphur
• Rhombic sulphur is the most common and stable allotrope of Sulphur.

Properties:

1. It exists as a rhombic octahedral structure.
2. It is pale yellow in colour.
3. The density of rhombic Sulphur is $2.06\mathrm{g}/\mathrm{ml}$
4. melting point is $112.8^{°}\mathrm{C}$
5. Rhombic Sulphur is insoluble in water and soluble in Carbon disulphide.

So, All the given properties of rhombic Sulphur are correct.
