Question

Draw the structure of 2,3-dimethylbutane.

 

Answer 1

Concepts and reason

IUPAC stands for the 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 the root name, prefix, and suffix. The longest chain tells the root name. Prefix tells the position and name of the substitutions present on the longest chain. Suffix tells the functional group present in the structure.

 

The given IUPAC name is 2,3-dimethylbutane. The root name is but.

The root name is but, which means that the longest chain has four carbon atoms.

 

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

From the given IUPAC name suffix is ane. So, the functional group is alkane.

 

The prefix name is 2,3 -dimethyl

Thus, the structure of 2,3-dimethylbutane is,

The prefix name is 2,3-dimethyl, which means two methyl groups are present at \(C-2,\) and \(C-3\) carbon atoms.
