Pentanol, Glucose, and unsaturated fatty acid, provides most accurate images of a molecule shape, very easy and fast to draw;points are carbon and hydrogen bond to the carbon. Covalent Bonds When two nonmetals bond, they often share electrons since they have similar attractions for them. Annette Caravetta Nitto, . hydrogen bond : The attraction between a partially positively charged hydrogen atom attached to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) and another nearby electronegative atom. CH3NH2c. * Provides a comprehensive introduction to this evolving and Water molecules are constantly on the move. 2. number of bonds in oxygen.
