    Given that the radius of \[N{{a}^{+}}\] ion is \[0.95\,\overset{o}{\mathop{A}}\,\] and that of \[C{{l}^{-}}\] ion is \[1.81\,\overset{o}{\mathop{A}}\,\], hence in the close packed lattice of \[C{{l}^{-}}\] ions, \[N{{a}^{+}}\] ions prefer to occupy

    A)  tetrahedral site               

    B)  octahedral site

    C)  cubic site          

    D)  trigonal site

    Correct Answer: B

    Solution :

                    Radius ratio, \[\frac{{{r}_{+}}}{{{r}_{-}}}=\frac{0.95\,\overset{o}{\mathop{A}}\,}{1.81\,\,\overset{o}{\mathop{A}}\,}=0.524\] Therefore, \[N{{a}^{+}}\] ions prefer to occupy octahedral site (0.414 - 0.732).
