    In which transformation the change of hybridization and shape about underlined atom take place?

    A) \[\underline{C}{{H}_{3}}C{{H}_{3}}\xrightarrow{{}}\underline{C}H_{3}^{-}+CH_{3}^{+}\]

    B) \[N{{H}_{3}}+\underline{B}{{F}_{3}}\xrightarrow{{}}[{{H}_{3}}N\to \underline{B}{{F}_{3}}]\]

    C) \[{{H}_{2}}\underline{O}+{{H}^{+}}\xrightarrow{{}}{{H}_{3}}{{\underline{O}}^{+}}\]

    D) \[\underline{N}{{H}_{3}}\xrightarrow{{}}\underline{N}H_{2}^{-}+{{H}^{+}}\]

    Correct Answer: B

    Solution :

    [b] \[N{{H}_{3}}+\underline{B}{{F}_{3}}\xrightarrow{{}}[{{H}_{3}}N\to B{{F}_{3}}]\,or\,{{H}_{3}}\overset{\oplus }{\mathop{N}}\,-\underline{\overset{\oplus }{\mathop{B}}\,}{{F}_{3}}\] \[\ell P=0\]                          \[\ell p=0\] \[bp=3\]                          \[bp=4\] \[\underset{Plane\text{ }Triangle}{\mathop{s{{p}^{2}}}}\,\]                            \[\underset{Tetrahedral}{\mathop{s{{p}^{3}}}}\,\]
