Assertion: Diamond is an allotrope of carbon with a unique molecular structure.
Reason: Diamond is composed of carbon atoms arranged in a crystal lattice structure, where each carbon atom is covalently bonded to four other carbon atoms in a tetrahedral arrangement.
Both A and R are true and R is the correct explanation of A
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Allotropy is the property of an element to exist in different forms with different physical and chemical properties. Carbon is a unique element that exhibits allotropy, and diamond is one of its allotropes. Diamond is a transparent, colorless, and extremely hard material, making it a popular choice for use in jewelry, cutting tools, and industrial applications.
The unique molecular structure of diamond is what gives it its exceptional properties. The tetrahedral arrangement of carbon atoms in diamond creates a strong covalent bond between each atom, forming a rigid and stable crystal lattice structure. This arrangement results in the diamond's hardness and high thermal conductivity, as well as its ability to refract light, making it highly valued for use in jewelry.
In conclusion, the assertion that diamond is an allotrope of carbon with a unique molecular structure is true, and the reason provided explains the characteristics that make diamond a valuable material.
