Question

Specify the coordination geometry around and hybridization of N and B atoms in a $1:1$ complex of $BF_{3}$ and $NH_{3}:$

• A. N: Tetrahedral, $sp^{3}$; B: Tetrahedral, $sp^{3}$
• B. N: pyramidal, $sp^{3}$; B: pyramidal, $sp^{3}$
• C. N: pyramidal, $sp^{3}$; B: Planar, sp3$sp^{3}$
• D. N: Pyramidal, $sp^{3}$; B: Tetrahedral, $sp^{3}$

Answer 1

Answer: (A)

In complex $[H_{3}N \to BF_{3}]$, both N and B attains $sp^{3}-$ hybridisation and acquires tetrahedral geometry
