Question

What is the molecule shown below?

Answer 1

Answer:

2,3 -Dimethyl pentane

Explanation:

The given molecule is 2,3-Dimethyl pentane.

First of all select the longest chain of C-C atom. This will be the parent name.

In given structure the longest chain is straight chain that contain five carbon. Thus the parent name will pentane and there is no double or triple bond the given structure is of alkane.

Than locate the positions of functional groups attached.

In given structure there are two methyl groups are present. Give the name in such a way that functional groups will have lowest number. In given case we will start from the left.

The first methyl group will have number 2 and second will have number 3.

The name will be,

2,3-Dimethyl pentane
