Which one of the following elements is unable to form MF-6-3- ion-BGaInAl

Question

Toppr Admin · Accepted Answer

B is unable to form MF3-x2212-6 ion-This is because -B3- has no vacant d orbitals- It has only on s and- 3 p orbitals in the valence shell-xA0-Hence- it can accept 4 electron -pairs and can form BF-x2212-4-therefore option A is correct-

Which one of the following elements is unable to form $M F_{6}^{3 -}$ ion?
$B$
$G a$
$I n$
$A l$

B is unable to form $M F_{6}^{3 -}$ ion.
This is because $B^{3 +}$ has no vacant d orbitals. It has only on s and 3 p orbitals in the valence shell.
Hence, it can accept 4 electron pairs and can form $B F_{4}^{-}$ .
therefore option A is correct.

Which one of the following elements is unable to form MF3−6 ion?BGaInAl

B is unable to form MF3−6 ion.This is because B3+ has no vacant d orbitals. It has only on s and 3 p orbitals in the valence shell. Hence, it can accept 4 electron pairs and can form BF−4.therefore option A is correct.
