question_answer 1)

In the following questions only one option is correct. Isostructural species are those which have the same shapeand hybridisation. Among the given species identify the isostructural pairs : (a) \[[N{{F}_{3}}and\,B{{F}_{3}}]\]           (b) \[[BF_{4}^{-}and\,NH_{4}^{+}]\]                (c)\[[BC{{l}_{3}}\,and\,BeC{{l}_{3}}]\]    (d) {\[N{{H}_{3}}and\,NO_{3}^{-}\]]

Answer:

(b) \[BF_{4}^{-}\to s{{p}^{3}}\] -hybridisation; Tetrahedral \[NH_{4}^{+}\to s{{p}^{3}}\]-hybridisation; Tetrahedral
