Concept introduction: The systematic naming of organic compound is given by IUPAC nomenclature. The naming of organic compound is done such that the structure of organic compound is correctly interpreted from the name.

Rules for writing structural formula from IUPAC are:

1. First identify the word root for the given compound.

2. The suffix used in the compound like –ene.

3. Identify the position, location, and number of the substituent bonded to the carbon chain.

Expert Solution

Answer to Problem 10.39P

The structure corresponding to 1−isopropyl−4−propylcyclohexene is shown in Figure 6.

Explanation of Solution

Rules for writing structural formula from IUPAC are

1. First identify the word root for the given compound.

2. The suffix used in the compound like –ene.

3. Identify the position, location, and number of the substituent bonded to the carbon chain.

The given name is 1−isopropyl−4−propylcyclohexene. The word root used in this is hex. It means structure contains six carbon atoms in a cyclic ring. The hydrocarbons that are attached to the longest chain are called substituents and they are written as prefix in alphabetical order. Therefore, the name suggests that one isopropyl substituents is attached to the first carbon atom and one propyl substituents is attached to the fourth carbon atom The double bond is present between first and second carbon atom.

Thus, the correct structure of 1−isopropyl−4−propylcyclohexene is shown below.
