Question

Boron is unable to form $BF_{6}^{3 -}$ ions due to.

A

Non –availability of d - orbitals

B

Small size of boron atom

C

Non – metallic nature

D

Less reactivity towards halogens.

Answer

Non –availability of d - orbitals

Explanation

Solution

: Due to non – availability of d – orbitals, boron is unable to expand its octet. Therefore, the maximum covalence of boron canont exceed 4.
