Which of the following statements is false?
(a) Gases are far less dense than liquids.
(b) Gases are far more compressible than liquids.
(c) Because liquid water and liquid carbon tetrachloride do not mix, neither do their vapors.
(d) The volume occupied by a gas is determined by the volume of its container.
Step 1 of 5) A second general reaction used to synthesize commercially important polymers is condensation polymerization. In a condensation reaction two molecules are joined to form a larger molecule by elimination of a small molecule, such as H2O. For example, an amine (a compound containing ¬NH2) reacts with a carboxylic acid (a compound containing ¬COOH) to form a bond between N and C plus an H2O molecule (Figure 12.36). Polymers formed from two different monomers are called copolymers. In the formation of many nylons, a diamine, a compound with the ¬NH2 group at each end, is reacted with a diacid, a compound with the COOH group at each end. For example, the copolymer nylon 6,6 is formed when a diamine that has six carbon atoms and an amino group on each end is reacted with adipic acid, which also has six carbon atoms. A condensation reaction occurs on each end of the diamine and the acid. Water is released, and N¬C bonds are formed between molecules. Table 12.6 lists nylon 6,6 and some other common polymers obtained by condensation polymerization. Notice that these polymers have backbones containing N or O atoms as well as C atoms.
