C
H2O
D
NH3
Verified step by step guidance1
Identify the types of intermolecular forces present in each compound by analyzing their molecular structure and polarity.
Recall that London dispersion forces are present in all molecules but are the only intermolecular forces in nonpolar molecules.
Examine each compound: CH3OH (methanol) has hydrogen bonding due to -OH group; H2O (water) has strong hydrogen bonding; NH3 (ammonia) also exhibits hydrogen bonding because of N-H bonds.
CCl4 (carbon tetrachloride) is a symmetrical molecule with nonpolar bonds, so it does not have dipole-dipole interactions or hydrogen bonding, only London dispersion forces.
Conclude that CCl4 is the compound that experiences only London dispersion forces between its molecules.
