Question

In which of the following species, the bond is non-directional?

• A. $NC{l}_3$
• B. $RbCl$
• C. $BeC{l}_2$
• D. $BC{l}_3$

Answer 1

Answer: (B)

$RbCl$

In the given options, $B$ is correct because electronegativity difference between $Rb$ and $Cl$ is more than 1.7, hence it proves that $RbCl$ is an ionic compound. Ionic compounds have non-directional bonds.
