Question

What are the most important kinds of INTERmolecular forces present in each of the following substances:
a) toluene C7H8
b) mercury, Hg
c) ammonia, NH3
d) ethanol, CH3CH2OH
e) chloroform, CHCl3

My attempt to answer follows. Would like to know if I'm on the right track, and if I'm wrong, why?
a) toluene, C7H8 dispersion within the hexane ring, along with 3 pi bonds, and a dipole-dipole with the C1 and the methyl group C
b) Hg is presented as a single atom so it cannot have INTERmolecular forces with only one molecule
c) ammonia NH3 is single molecule so it also cannot have INTERmolecular forces/ only INTRA
d) ethanol, CH3CH2OH will have a dipole-dipole between O and H and dispersion on the rest of the alkae chain
e) chloroform, CHCl3 dipole-dipole between the Cl and the C and a dispersion between the C and H

Explanation / Answer

a. toluene has pi - pi stacking, which happens because of pi rings in phenyl ring.. b. You can never have any pair of molecules or atoms without any intermolecular force. Atlease vanderwaals force is present between any two atoms. c. dipole -dipole forces exist d. H-bonding e. dipole-dipole
