Solution Summary

This response provides assistance on drawing structural formulas for molecular formulas and determines whether these formulas are polar.

Solution Preview

1 a) CH3Cl The C-Cl bond is polar due to the difference in electronegativity between the C and the Cl. I have shown the polarity on this using the dipole moment convention.

b) H2 Since both H's have exactly the same electronegativity there is no polar bond.

2) The only 2 possibilities are a ketone and an aldehyde.

3) Remember that formal charge is the number of electrons an atom wants to have relative to the number that is assigned to it. Lone pairs are completely controlled by an atom and so are assigned to that atom. Bonding pairs are shared so that only ½ of the bonding ...
