Question

Specify the coordination geometry and hybridisation of $N$ and $B$ atoms in a $1:1$ complex of $B{F}_3$ and $N{H}_3$.

• A. $N$ : tetrahedral, $s{p}^3$ ; $B$ : planar, $s{p}^2$
• B. $N$ : pyramidal, $s{p}^3$ ; $B$ : pyramidal, $s{p}^3$
• C. $N$ : pyramidal, $s{p}^3$ ; $B$ : planar, $s{p}^3$
• D. $N$ : tetrahedral, $s{p}^3$ ; $B$ : tetrahedral, $s{p}^3$

Answer 1

The correct option is D $N$ : tetrahedral, $s{p}^3$ ; $B$ : tetrahedral, $s{p}^3$

In a $1:1$ complex of $B{F}_3$ and $N{H}_3$, $N$ atom has tetrahedral geometry with $s{p}^3$ hybridization and $B$ atom has tetrahedral geometry with $s{p}^3$ hybridization.
