Question

why boron in unable to form bf6^3-

Answer 1

boron can't able to form bf6 because it have not p orbital so I can't extent its octet

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.
