Chapter 23.2, Problem 23.2WE

(a)

Interpretation Introduction

Interpretation:

The name of the organic compounds should be given.

Concept introduction:

Organic compounds are named systematically by using IUPAC rules.

Name of the organic compounds are given according to the number of carbon present in the molecule for example

A molecule having one carbon atom, the molecule name will start with meth etc.…

If any halogens are present in the molecule, the name of the halogens as follows.

Naming the substituted alkane:

1. (1) Name the parent alkane (long alkyl chain)
2. (2) Number the carbon
3. (3) Name and number the substituent

If the molecules have the multiple substituents, the compound named as di, tri, tetra, penta, ect.

If the molecules having functional group, the name of the compound is given below. Numbering should be starts from the functional group of the given molecule.

The given compound is an alcohol $\left(\text{OH}\right)$, the compound name end up with ol. The name of the compound is given according to the number of carbon atom.

Example is given below

The given compound is an acid ( $\text{COOH}$), the compound name end up with oic. The name of the compound is given according to the number of carbon atom.

The amides are derivatives of acids and it is named as the ending of alkane with amide.

For example

If the molecule is ester,

Esters end with “ate”

Example

The given compound is an aldehyde ( $\text{CHO}$), the compound name end up with al. The name of the compound is given according to the number of carbon atom.

The given compound is ketone ( $\text{CO}$), the compound name end up with one. The name of the compound is given according to the number of carbon atom.

The given compound is an amine ( ${\text{NH}}_{\text{2}}$), the compound name end up with amine. The name of the compound is given according to the number of carbon atom.

Answer to Problem 23.2WE

Answer

1. (1) The name of the given organic compounds is given below (a).

   

Explanation of Solution

To find: The name of the given organic compounds.

The name of the given organic compounds is 3-chloropentane.

Parent chain is identified and numbering is given for the compound. According to structure, third carbon is bearing ethyl group and totally it has five carbon atom therefore it is called as pentane and ethyl group in the side chain. According to the structure the name of the molecule is given above.
