    Graphite and diamond are :

    A)  polymorphs

    B)  allotropes

    C)  different crystal structure

    D)  all of the above

    Correct Answer: D

    Solution :

    Key Idea: In diamond carbon is \[s{{p}^{3}}\] hybridised and in graphite carbon is \[s{{p}^{2}}\] hybridised. Graphite and diamond are allotropes because they exist in two different structural forms in same physical state. They have different arrangement of atoms in crystal lattice. They are polymorphs.
