Both $A$ and $R$ are true but $R$ is not the correct explanation of $A$.

Vedclass · Answer

(B) Assertion $A$ is true: Boron cannot form $BF_{6}^{3-}$ because it lacks $d$-orbitals in its valence shell,which prevents the expansion of its octet.Reason $R$ is true: The size of the Boron atom is indeed very small.Conclusion: While both statements are true,the inability to form $BF_{6}^{3-}$ is primarily due to the absence of $d$-orbitals,not just the small size of the atom. Therefore,$R$ is not the correct explanation for $A$.

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: Boron is unable to form $BF_{6}^{3-}$.
Reason $R$: Size of $B$ is very small.
In the light of the above statements,choose the correct answer from the options given below.
