Question

Intermolecular Forces and the Triple Point of CO2 2) The relative strength of the intermolecular forces depends on the size (i.e of the molecules and include, in rough order of decreasing strength, ion-ion, hydrogen bonding, dipole dipole (polar), dipole-induced dipole (dispersion become th MW) and structure ion-dipole, dipole, and induced dipole-induced ) forces. The latter increases with molecular weight and can so e most predominant force. There are no ions in these liquids, and all the molecules are alike, leaving primarily hydrogen bonding, dipole -dipole, and disperson forces to consider What are the strongest intermolecular forces in acetone? What are the strongest intermolecular forces in methanol? What are the strongest intermolecular forces in 2-propanol? What are the strongest intermolecular forces in water? What are the strongest intermolecular forces in hexane?

Explanation / Answer

1. Primary intermolecular forces present in acetone is dipole-dipole forces,due to polar bond present which makes the overall acetone molecule polar.

2. The primary intermolecular force present in methanol is hydrogen bonding,due to presence of -OH bond.

3. Again it is similar to ethanol and this also has hydrogen bonding as primary intermolecular force.

4.Same as 2 and 3 , it has more intensive hydrogen bonding,due to presence of 2 -OH in single molecule.

5. Primary intermolecular force is induced dipole-induced dipole as the molecule is non-polar .
