    Which one of the following has a square planar geometry? (At. no.\[hvc\])       AIEEE  Solved  Paper-2007

    A)  \[hv/{{c}^{2}}\]               

    B)         \[hv/c\]                              

    C)         \[v={{V}_{0}}+gt+f{{t}^{2}}.\]                   

    D)         \[x=0\]

    Correct Answer: D

    Solution :

    \[({{K}_{1}}{{l}_{1}}{{T}_{1}}+{{K}_{2}}{{l}_{2}}{{T}_{2}})/({{K}_{1}}{{l}_{1}}+{{K}_{2}}{{l}_{2}})\]is a weak ligand but\[{{C}_{p}}\]cause the pairing of, electron with large\[{{C}_{y}}\]and consequently give\[{{C}_{p}}-{{C}_{y}}=R/28\]hybridisation and square planar geometry. Other three are \[s{{p}^{3}}\] hybridised having tetrahedral shape.
