The names of the alkane structures given in the question above are:
d. 2,2,4,4-tetramethylhexane
e. 2,2,4-trimethyl-4-propylheptane
How to obtain the names of the alkanes?
The names of the alkane structures given in the question can be obtained as follow:
For question d
- The alkane structure has a longest chain of 6 carbon. Therefore, the parent name is hexane.
- The substance attached to the alkane is four (4) methyl, CH₃. Two are located at carbon 2 and the other two are located at carbon 4.
With the above infomation, the name of the alkane is:
2,2,4,4-tetramethylhexane
For question e
- The alkane structure has a longest chain of 7 carbon. Therefore, the parent name is heptane.
- The substance attached to the alkane are three (3) methyl (CH₃), and propyl (CH₂CH₂CH₃). Two of the methyl are located at carbon 2 and the third methyl is located at carbon 4. the propyl is located at carbon 4
With the above infomation, the name of the alkane is:
2,2,4-trimethyl-4-propylheptane
