Question

Quizplus · Accepted Answer

NH₃ and CO are polar molecules. NH₃ has a trigonal pyramidal shape with a lone pair on nitrogen, leading to a net dipole moment. CO has a polar covalent bond due to the difference in electronegativity between carbon and oxygen. H₂ and CO₂ are nonpolar; H₂ is a homonuclear diatomic molecule, and CO₂ is linear with dipoles that cancel out.
