    Which of the following conversions involves change in both shape and hybridisation? [JEE Main 16-4-2018]

    A) \[C{{H}_{4}}\to {{C}_{2}}{{H}_{6}}\]  

    B) \[N{{H}_{3}}\to NH_{4}^{+}\]

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

    D) \[B{{F}_{3}}\to BF_{4}^{-}\]

    Correct Answer: A

    Solution :

     Both have \[s{{p}^{3}}\]hybridisation and tetrahedral shape.  Both have hybridisation. Shape of\[N{{H}_{3}}\] is pyramidal and shape of \[NH_{4}^{+}\]is tetrahedral. \[{{H}_{2}}O\]have hybridisation and\[{{H}_{3}}{{O}^{+}}\] have hybridisation. \[{{H}_{2}}O\]is bent shaped molecule and\[{{H}_{3}}{{O}^{+}}\] is pyramidal.  Both have hybridisation.
