For each of TWO molecules, methylamine and acrylonitrile , do the following:
1) Draw the lewis structure. Redraw (if needed) to show the correct bond angles.
2) Label every central atom with a molecular geometry and a hybridization.
3) Count up all pi bonds and all sigma bonds.
4) Draw the bonding orbitals of the sigma structure (flower pictures!). Annotate your bonds to indicate which orbitals are overlapping to produce bonds.
5) Draw the pi structure of your molecule. Annotate the drawing to indicate which orbitals are overlapping to form bonds.
and 
bonds between carbon and oxygen?
