    • 5.1: Drawing Chemical Structures
      Kekulé Formulas or structural formulas display the atoms of the molecule in the order they are bonded. Condensed structural formulas show the order of atoms like a structural formula but are written in a single line to save space. Skeleton formulas or Shorthand formulas or line-angle formulas are used to write carbon and hydrogen atoms more efficiently by replacing the letters with lines. Isomers have the same molecular formula, but different structural formulas
    • 5.4: Condensation Polymers
      Condensation polymers are any kind of polymers formed through a condensation reaction—where molecules join together—losing small molecules as byproducts such as water or methanol, as opposed to addition polymers which involve the reaction of unsaturated monomers.
    • 5.5: Condensation Polymers
      Formation of a condensation polymer produces \(H_2O\), \(HCl\), or some other simple molecule, which escapes as a gas. A familiar example of a condensation polymer is nylon, which is obtained from the reaction of two monomers.
    • 5.6: Addition Polymers
      An addition polymer is a polymer which is formed by an addition reaction, where many monomers bond together via rearrangement of bonds without the loss of any atom or molecule under specific conditions of heat, pressure, and/or the presence of a catalyst.
    • 5.7: Addition Polymers
      Addition polymers are usually made from a monomer containing a double bond.
    • 5.10: Cross-Linking
      The formation of covalent bonds which hold portions of several polymer chains together is called cross-linking. Extensive cross-linking results in a random three-dimensional network of interconnected chains.
