Answer “What is the IUPAC name for the compound shown”

Concepts and reason

IUPAC stands as international union of pure and applied chemistry. The IUPAC nomenclature has been used to identify organic compounds. The IUPAC name is composed of three parts: the root name, suffix and prefix.

Fundamentals

An IUPAC name is made up of three parts: root name, suffix and prefix.

The root name is given by the longest chain.

Prefix indicates the name and position of substitutions on the longest chain.

The suffix indicates the functional group in the structure.

Step – by – step

Step 1 of 3

Below is the structure of the compound.

The numbers indicate the longest chain. Hex is the root name.

Explanation | Common mistakes | Hint for next step

Six carbon atoms make up the longest chain. So, the root name for the given structure is hex. Choose the longest chain so that the substituents have the lowest numbers.

Step 2 of 3

The longest chain has three substituents. There are two methyl and one ethyl groups.

The prefix is 3-ethyl-2,2-dimethyl.

Explanation:

Two methyl groups are substituted at C-2 carbon and one ethyl group is substituted at C-3 carbon. So, the prefix is 3-ethyl-2,2-dimethyl.

Step 3 of 3

The suffix is ane

Thus, the IUPAC name of the given structure is 3-ethyl-2,2-dimethylhexane.

Explanation

Alkane is the functional group. So, the suffix is ane

Answer

The IUPAC name for the given structure is 3-ethyl-2,2-dimethylhexane.
