WebA saturated fatty acid has all bonding positions between carbons occupied by hydrogens. The melting points for the saturated fatty acids follow the boiling point principle observed previously. Melting point principle: as the molecular weight increases, the melting point increases. This observed in the series lauric (C12), palmitic (C16 ... WebGeometric isomers, like all isomers, have different physical properties. For example, the boiling point of cis- and trans -1,2-dichloroethene ( Figure 4.3) are 60 °C and 47 °C, respectively. The two C—Cl bond moments of the trans isomer cancel each other, and the compound has no dipole moment.
