Consider diamond and graphite. Which of the following is true?
(A) Graphite should have a higher melting point than diamond.
(B) Differences in composition account for the different properties of gaphite and diamond.
(C) Amorphous soilds are likely to have highe meltong points than their crystalline counterparts.
(D) Introducing an impurity into a crystalline material should increase the observed melting point.
(E) The carbon atoms in diamond are sp32 hybridized.

    E is correct. As we have four bondings, and no one is in any way to be preferred, it is logical that they are spĀ³ hybridized.

    I don't see any correct answers listed although E comes the closest. If you had sp3 instead of sp32 I would go with E being correct.
