Due to the non-symmetrical shape of the molecule (bent), the molecule itself is polar (it has a \(\delta-\) and \(\delta+\) side). Carbon tetrachloride has four polar covalent bonds. It is a ...

Each redox state of carbon (Fig. 2) is associated with ... differentiation among the functional groups present in a molecule—through shape recognition of a precursor molecule.

that is also attached to the α carbon. The R groups have a variety of shapes, sizes, charges, and reactivities. This allows amino acids to be grouped according to the chemical properties of their ...
