What are some of the differences between allotropes of carbon?
the crystalline allot-ropes of carbon are Diamond and Graphite their differences are,Diamond1- every carbon is sp3 hybridized and tetrahedraly attached to four other carbon atoms at the angles of 109.5, 2- No free electrons, so nonconductor of electricity, 3-Hardest natural material due to absence of any cleavage axis.Graphite1- every carbon is sp2 hybridized and trigonaly attached to three other carbon atoms at the angles of 120, 2- one free electron (weakly held through pi bonding) per atom so is conductor of electricity, 3- soft material due to presence of cleavage axis along sheet like structure.

Why is diamond such a hard ad nonreactive substance?
Carbon atoms can bond to other carbon atoms in a variety of ways, but when they bond in a network, with all the atoms bonding to all the other atoms that surround them, it is a very strong bond, stronger than the bonds formed in other minerals. Strong bonds are, by definition, hard to break. Hence the material is very hard. Scratching it requires breaking bonds.
