Based on VSEPR theory, the number of 90 degree F−Br−F\mathrm{F}-\mathrm{Br}-\mathrm{F} angles in BrF5\mathrm{BrF}_5 isBased on VSEPR theory, the number of 90 degree F-Br-F angles in BrF_5 is

Correct answer

0

Step-by-step solution

In BrF5\mathrm{BrF}_5 number of electrons =6=6 (1lp+5bp)(1 l p+5 b p) So, the structure is supposed to be square pyramidal but will be distorted because of additional lp- bpb p interaction. Based on VSEPR theory, the number of 90 degree F-Br-F angles in BrF_5 is
Additional lp−bp\quad l p-b p interaction reduces the all bond angle and do not let any angle to be 90∘90^{\circ}. Chemical bonding Conceptual IV
