Answer to Problem 128A
The structural formula for heptane is represented as follows:
Explanation of Solution
With IUPAC names, it is easy to draw the structure of the compounds. Firstly, draw the hydrocarbon chain (parent chain), then identify the substituents groups or functional groups in the hydrocarbon name and attach them if present at proper positions. And lastly, add the hydrogen atoms wherever required.
In heptane, there is a long continuous carbon chain containing seven carbon atoms. Thus, the structural formula for heptane is given as follows:

Answer to Problem 128A
The structural formula for 2-methyl-3-hexene is represented as follows:
Explanation of Solution
With IUPAC names, it is easy to draw the structure of the compounds. Firstly, draw the hydrocarbon chain (parent chain), then identify the substituents groups or functional groups in the hydrocarbon name and attach them if present at proper positions. And lastly, add the hydrogen atoms wherever required.
In 2-methyl-3-hexene, the longest continuous chain is six carbon atoms chain that has a double bond at the third carbon. There is a methyl substituent that is present on the second carbon in this long continuous chain. Thus, the structural formula for 2-methyl-3-hexene is given as follows:

Answer to Problem 128A
The structural formula for 1,3-diethylbenzene is represented as follows:
Explanation of Solution
With IUPAC names, it is easy to draw the structure of the compounds. Firstly, draw the hydrocarbon chain (parent chain), then identify the substituents groups or functional groups in the hydrocarbon name and attach them if present at proper positions. And lastly, add the hydrogen atoms wherever required.
In 1,3-diethylbenzene, the parent ring is benzene, and ethyl groups are substituted on the first and the third carbon atoms. Thus, the structural formula for 1,3-diethylbenzene is given as follows:
