Question

Diamond is an allotrope of:
1. Boron
2. Carbon
3. Silicon
4. Arsenic

Answer 1

Correct Answer - Option 2 : Carbon

The correct answer is Carbon.

• Diamond is an allotrope of Carbon.
• The phenomenon of the existence of an element in two or more forms that have different physical properties but identical chemical properties is called allotropy and the different forms are called allotropes.
• Some chemical elements are known to exist in two or more different forms because the atoms are bonded together in different manners.
• The most common example is Carbon which exists in Diamond, graphite, fullerenes, etc.
• Allotropy is for elements and not for compounds.
• For example, water and ice are not allotropes.
• Carbon has allotropes such as Diamond which is an extremely hard, transparent crystal in which atoms are arranged in a tetrahedral lattice.
