    A molecule \[C{{H}_{3}}C{{H}_{2}}MgBr+C{{H}_{3}}COC{{H}_{3}}\] contains two a, two TC-bonds and one lone pair of electron in the valence shell of A. The arrangement of lone pair as well as bond pairs, is

    A)  square pyramidal   

    B)  trigonal planar

    C)  linear               

    D)  tetrahedral

    Correct Answer: B

    Solution :

                                    The valence shell of A has two \[Hl>HBr>HCl~\]-bonds and one lone pair of electrons. Thus, it has planar triangular geometry. It may be mentioned that bond pairs involved in the formation of Ti-bonds, are not considered whereas deciding the geometry of the molecule.
