- Nitrogen-containing functional groups can interact with lithium atoms.
- Selective reaction of one alcohol among many in complex molecules can be achieved by the use of a catalyst that forms a single covalent bond to a nearby functional group.
- The key to the effects of functional groups lies in what are called "nonbonded interactions", which occur between atoms with no chemical bonding.
- Functional groups is a term that refers to groups of atoms that give a molecule specific characteristic properties.
