Question

Fluoride can form polyfluorides $F_3^{-}$ - True or False?

• A. True
• B. False

Answer 1

The correct option is B False

Due to the absence of vacant d-orbitals (Electronic configuration of ‘F’ is $\left(1s^{2}2s^{2}2p^5\right)$ in Fluorine,polyfluorides are not formed but chlorine, bromine and iodine form polyhalides $C{l}_3^{-},B{r}_3^{-}and{I}_3^{-}$ due to presence of d-orbital.
