Question

    Diamond is harder than graphite because of which of the

    following reason?
    A Tetrahedral structure of diamond Correct Answer Incorrect Answer
    B Difference in layers of atoms Correct Answer Incorrect Answer
    C Difference in crystalline structure Correct Answer Incorrect Answer
    D Greater Specific heat of diamond Correct Answer Incorrect Answer

    Solution

    Diamond and Graphite both are allotropes of carbon. In Diamond, the molecules have strong force between its molecules while graphite has loose force of attraction between its molecules. Diamond has less intermolecular space between molecules while graphite has more intermolecular space between its molecules. Due to this, graphite is soft and slippery in nature whereas diamond is the hardest substance known to man.
