Question

$Br{F}_3$ is a liquid which considerably undergoes self ionization to form cationic and anionic species.
$2Br{F}_3\rightleftharpoons [Br{F}_2{]}^{+}+[Br{F}_4{]}^{-}$
Based on $VSEPR$ theory, how many ${90}^o$ $F-Br-F$ bond angles are there in anionic species?

• A. 4
• B. 5
• C. 3
• D. 2

Answer 1

The correct option is A 4

$2Br{F}_3\rightleftharpoons [Br{F}_2{]}^{+}+[Br{F}_4{]}^{-}$

There are $4$ 90${}^o$ $F-Br-F$ bond angles in anionic species.
