$\huge{\bf{\underline{\underline{Answer:-}}}}$

Boron is a non-metallic element. It is electron-deficient. It does not possess d orbitals in its valence shell. .Therefore, boron is unstable to form BF6 3- ion.

Answer:

Due to absence of d-orbital

Explanation:Boron being electron defficient doesn't have d-orbital and so it is unable to form BF6**3
