Question

Which of the following molecule is not hypovalent

• A. $AlC{l}_3$
• B. $AlB{r}_3$
• C. $Al{F}_3$
• D. All are hypovalent Because $Al{F}_3$ is ionic compound

Answer 1

The correct option is C $Al{F}_3$

$Al{F}_3$ is ionic and during the formation of ionic bond, octects of $A{l}^{3+}$ and $F^{-}$ have been completed. $AlC{l}_3$ and $AlB{r}_3$ are covalent and hypovalent.
