NH₃ shape:
ASquare planar
BLinear
CTetrahedral
DTrigonal pyramidal (sp³ with 1 lone pair)
Answer & Solution
Correct answer: D. Trigonal pyramidal (sp³ with 1 lone pair)
NH₃: sp³ N with 3 bond pairs + 1 lone pair. Geometry = trigonal pyramidal. Bond angle ≈ 107° (slightly less than tetrahedral 109.5° due to LP-BP repulsion). Lone pair makes N a Lewis base/nucleophile.
