Question

Boron cannot form which one of the following anions?
(1) BO-2
(2) BF3-6
(3) BH-4
(4) B(OH)-4
A) Option 1 B) Option 2 C) Option 3 D) Option 4

Answer 1

Boron cannot form BF63− anions due to absence of 2d orbitals in boron. Since 2d orbitals are not present in boron, it cannot expand its octet beyond 8. BF 6 3− anion will have 12 valence electrons around B.
