High molecular weight
B
Linear molecular shape
C
Polarity
D
Nonpolar covalent bonds
Verified step by step guidance
1
Understand that water (H₂O) is a polar molecule due to the difference in electronegativity between hydrogen and oxygen atoms.
Recognize that the oxygen atom is more electronegative than the hydrogen atoms, causing a partial negative charge on the oxygen and a partial positive charge on the hydrogens.
Visualize the bent shape of the water molecule, which contributes to its overall polarity, as the dipole moments do not cancel out.
Identify that the polarity of water molecules allows them to form hydrogen bonds, which are weak attractions between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another.
Conclude that the property of polarity in water molecules is what enables the formation of hydrogen bonds among adjacent molecules.
