Question

The geometry of $NH_{3}$ molecule can be best described as :

• A. Nitrogen at one vertex of a tetrahedron, the other three vertices being occupied by the hydrogen.
• B. Nitrogen at the center of tetrahedron, three hydrogen.
• C. Nitrogen at the center of an equilateral triangle, three comers being occupied by three hydrogen.
• D. Nitrogen at the junction of three open ends being occupied by three hydrogens.

Answer 1

Answer: (B)

$NH_{3} \rightarrow \text{Hybridisation } \rightarrow sp^{3} \rightarrow \text{Geometry } \rightarrow \text{Tetrahedral}$
