  • Question 9/10
    4 / -1

    If the anions (A) form hexagonal closest packing and cations (C) occupy only 2/3 of the octahedral voids in it, then the general formula of the compound would be

    Solutions

    In HCP, the number of octahedral void is equal to the number of atoms. Hence, the formula is AC2/3 i.e. A3C2.
