The handling of this chemical may incur notable safety precautions. it is not a symmetrical molecule. We learned in Chapter 1 that organic molecules generally adopt three dimensional structures in which the electron pairs in the chemical bonds are as far away from each other as possible according to the Valence Shell Electron Pair Repulsion Model (VSEPR). The central carbon is double bonded to O. Molecule Polarity. 1 sigma bond between C and O = 1. The stronger the force of attraction in between the bonding atoms, the smaller is the length of the bond. Ketones are named by replacing the-e in the alkane name with -one.
