Question

What is the iupac name of the following compound?

2,2-dimethyl-4-ethylheptane

Answer 1

The IUPAC name of the compound 2,2-dimethyl-4-ethylheptane is 3-ethyl-2,2-dimethylheptane.

Step-by-step explanation:

The IUPAC name of the compound 2,2-dimethyl-4-ethylheptane is 3-ethyl-2,2-dimethylheptane.

When naming this compound, we start by identifying the longest continuous chain of carbon atoms, which in this case is a heptane. There are two one-carbon substituents on the second carbon atom and a two-carbon substituent on the third carbon atom. Hence, the compound is named 3-ethyl-2,2-dimethylheptane.

Answer 2

The IUPAC name of the compound has already been given which is 2,2-dimethyl-4-ethylheptane.

Step-by-step explanation:

The IUPAC (International Union of Pure and Applied Chemistry) is an authority in chemistry that provides a guideline and standardized methods in the naming of compounds formed from the periodic table.

In order the give an IUPAC name to a compound, certain steps needs to be followed, these includes:

--> Identify the functional group in the compound as this will form the suffix. For example if the functional group is an alkane the suffix will be -ane.

--> Identify the longest carbon chain (it may not be a straight chain) that contains the functional group. This forms the prefix. Example: if the longest carbon chain is 7 carbon atoms then the prefix will be hept-

--> All the carbons of the longest chain should be numbered

--> Identify branched groups on the chain and name them according to the number of carbon atoms. They usually end with -yl.

--> Finally, combine the elements of the name is a single word.

The structural formula of the IUPAC compound can be found in the attached file for a better understanding. The branched groups are circled.
