Is water a polar or nonpolar molecule?
A
Nonpolar
B
Polar
Verified step by step guidance1
Understand the concept of polarity: A molecule is polar if it has a net dipole moment due to the presence of polar bonds and an asymmetrical shape. Nonpolar molecules have no net dipole moment.
Examine the structure of a water molecule: Water (H₂O) consists of two hydrogen atoms covalently bonded to one oxygen atom.
Consider the electronegativity of the atoms: Oxygen is more electronegative than hydrogen, meaning it attracts the shared electrons more strongly, creating polar bonds.
Analyze the molecular geometry: Water has a bent shape due to the two lone pairs of electrons on the oxygen atom, which causes an asymmetrical distribution of charge.
Determine the overall polarity: Due to the polar bonds and the bent shape, water has a net dipole moment, making it a polar molecule.
