Solution:
Diamond:
1. It has a glasslike grid
2. In precious stone, every carbon molecule is sp3 hybridized and attached to four other carbon particles through a sigma bond.
3. It has an unbending covalent bond network which is hard to break.
4. The C-C bond length in jewel is 154 pm.
5. It goes about as an electric cover.
Graphite:
1. It has a layered design
2. In graphite, every molecule is sp2 hybridized and is clung to three other carbon iotas through a sigma bond. The fourth electron frames a pi bond.
3. It is very delicate and its layers can be isolated without any problem.
4. The C-C bond length in graphite is 141.5 pm.
5. It is a decent conveyor of power.
