Identify the pair in which the geometry of the species is T-shape and square pyramidal, respectively are __________.                                                                                                   [JEE Online 15-04-2018]

A) \[Cl{{F}_{3}}\]and \[IO_{4}^{-}\]

B) \[lCl_{2}^{-}\] and \[lC{{l}_{5}}\]

C) \[lO_{3}^{-}\] and \[l{{O}_{2}}F_{2}^{-}\]

D) \[XeO{{F}_{2}}\]and \[XeO{{F}_{4}}\]

Correct Answer: D

Solution :

According, to VSEPR theory \[Xe\](in \[XeO{{F}_{2}}\]) Has fine electron pairs with three bonding pair. This means its geometry is T-Shaped. Similarly, \[Xe\]in \[XeO{{F}_{4}}\] has a hybridizah on of \[s{{p}^{3}}{{d}^{2}}\] Thus its geometry is square-pyramidal
