This is because of the attraction bewteen the positive and negative ends of the molecule and also because of the distribution of electrons on the molecule that make it temporarily negative or positive. With one machine, you can create nearly any shape to satisfy your rapid prototyping needs. The enolic form of acetone is shown in the figure. The molecule is a triangular planar molecule so the bond angles on C3H6O are 120 degrees. Bond dissociation energy of a covalent bond is in the range 209-418 kJmol-1.
