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

A)  \[CI{{F}_{3}}\]          

B)  \[B{{F}_{3}}\]

C)  \[Al{{F}_{3}}\]          

D)  \[N{{F}_{3}}\]

Correct Answer: A

Solution :

 In\[CI{{F}_{3}}\]all bonds are not equal due to trigonal bypyramidal (\[s{{p}^{3}}d-\]hybridisation) geometry of\[Cl{{F}_{3}}\]molecule. \[B{{F}_{3}}\]and\[Al{{F}_{3}}\]show trigonal symmetric structure due to \[s{{p}^{2}}-\]hybridisation. \[N{{F}_{3}}\]shows pyramidal geometry due to\[s{{p}^{3}}\]hybridisation
