To determine which of the given molecules are polar, we will analyze each molecule based on its structure and the electronegativity of its constituent atoms. A molecule is considered polar if it has a net dipole moment that is not equal to zero. ### Step-by-Step Solution: 1. **Water (H₂O)**: - Structure: H₂O has a bent shape due to the two lone pairs on oxygen. - Electronegativity: Oxygen is more electronegative than hydrogen. - Dipole Moment: The dipole moments from the O-H bonds do not cancel out due to the bent shape, resulting in a net dipole moment. ...
