Question

Among the following how many are allotropes of sulphur.
Fullerene, Milk of Magnesia, Graphite, Rhombic, β-Monoclinic, γ-Monoclinic, α-Monoclinic.​

Answer 1

Answer:

Explanation:

Sulphur mainly exists in two forms of allotropes: Rhombic and Monoclinic forms.

Out of these, rhombic allotrope (yellow in color) of sulphur is the most stable allotrope of sulphur.

The rhombic form gets converted to monoclinic when the rhombic form is heated at a temperature greater than 370 K.

Rhombic sulphur is also called octahedral sulphur.

Hence, option A is correct.
