2. Chapter 1: Bonding and Isomerism Methyl butyrate and propyl acetate are both organic flavors that are found in apples and pears respectively and are structural isomers. Structural Isomers are compounds that have the molecular formula (C5H10O2), but have different connectivity hence different structural formulas.

3. Bonding and Isomerism Questions ? Why does sucrose melt at 1850C while table salt melts at 801o C? Why do both substances dissolve in water and olive oil does not? Why does methyl butyrate smell like pears while propyl acetate smell like apple yet they have the same number and kind of atoms? Bonding is the key to the structure, physical properties and chemical behavior of different kinds of matter.
