Formaldehyde
Formaldehyde, H2CO, is a colorless gas that consists of two hydrogen, a carbon, and an oxygen. As shown in the diagram the carbon (C) is the central atom with two hydrogen (H) and one oxygen (O) hanging off of it. The oxygen double bonds to the carbon and still has two unshared pairs of electrons left over, as shown below.
Polarity
The molecule of H2CO is polar because the oxygen end of the bond is more negative than the hydrogen ends of the bond.
<-|- <-|-
O = C - H

H
The arrows above are pointing from the more positively charged components to the more negatively charged components of the molecule; there is a arrow pointing from the carbon to the oxygen and arrows pointing from each of the hydrogen to the carbon.
*There should be an arrow pointing from the bottom hydrogen to the carbon but I was unable to put it onto this diagram.

Forces of Attraction
If H2CO was bonded to itself, the forces of attraction involved would be:
London Dispersion Forces
Very weak attraction forces due to the constant movement of electrons around atoms.
Dipole - Dipole Attraction Forces
An electro-static attraction between the positive end of a molecule and the negative end of another. [represented by a dotted line]
O = C -- H - - - - - - O = C -- H

H H
Hydrogen Bond
A covalent bond temporarily forms between a hydrogen (H) and either a nitrogen (N), oxygen (O), or a fluorine (F). [represented by a solid line]
O = C -- H --------- O = C -- H
