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-hybridization and possesses two axial Cl - F bonds and one equatorial bond. Two lone pairs are at equatorial position and give rise to bent 'T' shape to \[Cl{{F}_{3}}.\]
