Document Summary

T ese compounds have the same molecular formula (c2h6o), yet they dif er from each other in the way the atoms are connected that is, they dif er in their constitution. As a result, they are called constitutional isomers. Constitutional isomers have dif erent physical properties and dif er- ent names. T e f rst compound is a colorless gas used as an aerosol spray propellant, while the second. Reactions are a result of electron movement compound is a clear liquid, commonly referred to as alcohol, found in alcoholic beverages. Constitutional isomers have the same formula, but differ in atom connections or the way the atoms are bonded (ch3och3 vs ch3ch2oh); their names and physical properties are different. According to the structural theory of matter, each element will generally form a predictable number of bonds. For example, carbon generally forms four bonds and is therefore said to be tetravalent. Nitrogen generally forms three bonds and is therefore trivalent.
