Step 1I'll solve this problem step by step, explaining why NH^3 (ammonia) is classified as a polar molecule:
Step 2: Understand Molecular Structure
Ammonia (NH3) has a trigonal pyramidal molecular geometry. The central nitrogen atom is bonded to three hydrogen atoms, with one lone pair of electrons on the nitrogen.
Final Answer
1. It has polar N-H bonds 2. Its trigonal pyramidal geometry is asymmetric 3. The lone pair on nitrogen creates an uneven charge distribution 4. These factors result in a net dipole moment, making NH^3 a polar molecule.
