Problem
Identify polar molecules from molecular structures.
Step-by-step solution
Polar molecules have a net dipole moment. Molecules with symmetrical structures and identical surrounding atoms are nonpolar. Molecules with asymmetrical structures or different surrounding atoms are polar.
Answer
NH3, SF4, SO2, CH2Cl2 (cis isomer), CH2Cl2 (trans isomer)
