In which of the following molecules are all the bonds not equal?

A) \[Al{{F}_{3}}\]                  

B) \[N{{F}_{3}}\]

C) \[Cl{{F}_{3}}\]                                   

D) \[B{{F}_{3}}\]

Correct Answer: C

Solution :

Cl in\[Cl{{F}_{3}}\]has\[s{{p}^{3}}d\]hybridisation and possess two axial Cl-F bonds and one equatorial bond. Two lone pairs are at equatorial positions give rise to bent T' shape to \[Cl{{F}_{3}}.\]
