Answer 1

General guidance

Concepts and reason

IUPAC stands for international union of pure and applied chemistry. IUPAC has given a nomenclature to name the organic compounds. The IUPAC name consists of three parts: root name, prefix and suffix.

Fundamentals

The three parts of an IUPAC name are root name, prefix and suffix.

The longest chain gives the root name.

Prefix gives the position and name of the substitutions present on longest chain.

Suffix gives the functional group present in the structure.

Step-by-step

Step 1 of 3

The given structure of the compound is shown below.

The longest chain is indicated by the numbers. The root name is hex.

Explanation | Common mistakes | Hint for next step

The longest chain has six carbon atoms. So, the root name for the given structure is hex. Select the longest chain such that, the substituents have lowest numbers.

Step 2 of 3

Three substituents are present on the longest chain. They are two methyl groups and one ethyl group.

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.

[Common mistake]

Make sure that the substituents are named in an alphabetical order.

Step 3 of 3

The suffix is ane

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

Explanation

The functional group is alkane. So, the suffix is ane

Answer

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

Answer only

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