IMF and Liquid properties

As water boils, the intermolecular forces break while the forces within the molecule stay in tact since they are stronger. Rank these in order of strongest to weakest: covalent bond London forces hydrogen bond dipole-dipole attraction

• dipole-dipole>covalent bond>hydrogen bond>London

• London>dipole-diple>hydrogen bond>covalent bond

• covalent bond>hydrogen bond>dipole-dipole>London

• hydrogen bond>dipole-dipole>London>covalent bond
