FIGURE 9.9 Butane and isobutane have the same atoms but different shapes. Isomers usually have somewhat different properties. For example, straight-chain molecules generally have higher boiling and melting points than their branched-chain isomers. The boiling and melting points of iso-butane are -12C and -160C, respectively. Compare these values with the boiling and melting points of butane in Table 9.2. Do these two compounds follow the general trend?

Hydrogen Peroxide: Hydrogen peroxide is also odorless and colorless. Its used as an antiseptic to kill germs on cuts. Its also used as bleach to remove color form hair. A: You can tell that they are different compounds from their very different properties. Carbon dioxide is a harmless gas that living things add to the atmosphere during respiration. Carbon monoxide is a deadly gas that can quickly kill people if it becomes too concentrated in the air.
