Question

difference between diamond and graphite

Answer 1

hey mate here is your answer:-

Diamond and graphite are both giant covalent substances made entirely of carbon atoms. Both have chemical formula , but they do not have a molecular formula.

Molecular structure

Diamond: Giant covalent structure, with each carbon covalently bonded to four other carbon atoms in a tetrahedral arrangement to form a rigid structure.

Graphite: It is also Giant covalent structure, with each carbon covalently bonded to three other carbon atoms in a hexagonal arrangement.

Hardness

Diamond: Extremely hard. Due to rigid, tetrahedral arrangement of carbon atoms.

Graphite: Soft. Layers of hexagonally arranged carbon atoms can slide over one another.

Electrical conductivity

Diamond: Insulator. Mobile electrons are absent. All four valence electrons are used in covalent bonds.

Graphite: Conductor. Three out of four valence electrons are used for covalent bonding with other carbon atoms. Remaining valence electrons can be delocalised across the planes of carbon atoms.
