    The relative arrangements of atoms in a molecule can be studied only if we know:

    A) structural formula

    B) molecular formula

    C) empirical formula

    D) none of the above

    Correct Answer: A

    Solution :

    The relative arrangement of atoms in a molecule can be studied by knowing structural formula of the compound. Molecular formula of a compound indicate the different elements and the exact number of different elements present in that compound, e.g., \[{{C}_{6}}{{H}_{12}}{{O}_{6}}\]is molecular formula of glucose. Empirical formula only give us the ratio in which different elements are present in that compound, e.g., empirical formula for glucose is \[{{C}_{1}}{{H}_{2}}{{O}_{1}}.\]
