Question

Name a molecule that has a trigonal pyramidal shape.

Answer 1

Explanation:

• Trigonal pyramidal structure is a molecular structure.
• In this structure, one atom is at apex and three atoms form the trigonal base.
• Because of lone pair-bond pair repulsion, Trigonal pyramidal structure is formed.
• In Ammonia (${\mathrm{NH}}_3$), the Nitrogen ($\mathrm{N}$) has a lone pair that repulses the three strong intermolecular hydrogen bonding.

Therefore, Ammonia (${\mathrm{NH}}_3$) is a molecule that has a trigonal pyramidal structure.
