Hello, thank you! Also, for the second question, could you determine the answer by finding what forces the molecules has, whether it is dispersion or dipole-dipole or hydrogen bonding and then determine the best conductor of electricity?

Not really. As far as electrical conductivity, you are more interested in intramolecular forces than you are in intermolecular forces, and also the number of ions present. For example, 1 M CaCl2 is a better conductor than 1 M NaCl because it produces more ions.
