Interpretation Introduction

Interpretation:

The systematic IUPAC name, constitutional isomers and chiral center of each group substituent in the given molecules (molecular formula) should be draw and identified.

Concept introduction:

1. IUPAC Nomenclature Method

The many of organic compounds can be named using certain rules given by IUPAC (International Union for Pure and applied chemistry). The IUPAC name consists of three parts in major namely Prefix suffix and root word.

Prefix: It represents the substituent present in the molecule and its position in the root name.

Suffix: denotes the presence of functional group if any in the molecule. It can be an alkene, alkyne, alcohol, carboxylic acid, alcohol etc...

(i). The alkynes molecules, suffix will be ‘yne’. (or)

(ii). Saturated ‘alkane’ molecule, suffix will be ‘ane’.

Root word: represents the longest continuous carbon skeleton of the organic different organic molecules.

2. Constitutional Isomers: The many of organic compounds having same molecular formula but different chemical forms (or) structures. In other words stereo chemical isomers typically have different connectives but differ in spatial arrangements.

3. Chiral center: Chiral molecules contain at least one carbon atom with four non-identical substitutions (or) groups this type of molecule is called a chiral center (or) asymmetric carbon.
