Question

Why is Boron unable to form BF6 3- ion?

Answer 1

Beyond this value, boron will become unstable and not be able to form BF6 3- ions. Boron is a non-metallic element. It is electron-deficient. It does not possess d orbitals in its valence shell.

Answer 2

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\purple{R}}}}$

❤⭐ :REASON:⭐❤

• ❤.. Due to $\red{\tt{Non}}$_$\purple{\tt{availability}}$ of$\orange{\tt{d}}$ orbitals,boran is unable to expand its$\green{\tt{Octet}}$.
• ❤...Therefore,the maximum cobalence of boran cannot exceed4.
