Multiple Choice
Which of the following intermolecular forces are most significant in determining the physical properties of water (H2O)?
A
Hydrogen bonding
B
Ionic bonding
C
London dispersion forces only
D
Dipole-dipole interactions only
Verified step by step guidance1
Identify the types of intermolecular forces present in water (H\_2O). Water is a polar molecule with a bent shape, which means it has a permanent dipole moment.
Recall that water molecules can form hydrogen bonds because the hydrogen atoms are bonded to a highly electronegative atom (oxygen), and there are lone pairs on the oxygen atom.
Understand that hydrogen bonding is a special, strong type of dipole-dipole interaction that occurs when hydrogen is bonded to N, O, or F, making it stronger than regular dipole-dipole forces.
Compare hydrogen bonding to other intermolecular forces: London dispersion forces are present in all molecules but are weaker, and ionic bonding is not relevant here because water is a molecular compound, not ionic.
Conclude that hydrogen bonding is the most significant intermolecular force affecting water's physical properties such as its high boiling point, surface tension, and heat capacity.
