Question

Boron is unable to form BF$_6^{-3}ion$Explain​

Answer 1

Answer:

Boron is the first member of Group 13 and hence, it does not have any d-orbitals and hence, it cannot extend its octet. Complete answer: ... In BF63 - , boron is attached with 6 fluorine atom which makes its unstable. Hence, we can conclude that boron is unable to form BF63 - ions due to non-availability of d orbitals.
