Question

what are the types of covalent bonds those link carbon atoms in diamond and graphite?​

Answer 1

Explanation:

• each carbon atom forms three covalent bonds with other carbon atoms.
• the carbon atoms form layers of hexagonal rings.
• there are no covalent bonds between the layers.
• there is one non-bonded - or delocalised - electron from each atom.
• Carbon has an electronic arrangement of 2,4. In diamond, each carbon shares electrons with four other carbon atoms - forming four single bonds. In the diagram some carbon atoms only seem to be forming two bonds (or even one bond), but that's not really the case.
