Interpretation Introduction

Interpretation:

The systematic (IUPAC) name of each group substituent in the given organic molecules should be draw and identified.

Concept introduction:

The several organic compounds can be named by 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: Represents the substituent present in the molecule and its position in the root name.

For example the saturated hydrocarbons not only from only carbon-hydrogen bonds rather than the carbon-carbon bonds that have added hydrogen atoms. These alkanes have to prefix ‘cyclo’ due to the configuration of rings of carbon atoms.

Suffix: Denotes the presence of functional group if any in the molecule. It can be an alkane, alkene, alkyne, alcohol, carboxylic acid, alcohol etc. For example alkene molecules, suffix will be ‘ene’. (Or) If the presence of completely saturated alkane molecules, suffix will be ‘ane’.

Root word: It represents the longest continuous carbon skeleton of the organic molecule.

The given molecule (a) is drawn as above, in the case the carbonyl group is part of carbonyl group of a five membered ring, so the given molecule is cyclopentane-1-one. In the given molecule the parent carbon skeleton is cyclic in nature which contains of 5 carbons one keto group (-C=O). Hence root name of the molecule is ‘cyclopentane-1-one’. Since it is an alkane with five carbons, one keto then ‘1-pentanone’ will be the functional carbon chain name.

Further the molecule (a) one cyclic ketone, the carbonyl group is at (C₁) place, next identified one propyl and one methyl groups present at (C₂ and C₃) axial and equatorial positions is (2S, 3R)-3-methyl-2-propylcyclopentanone, which are organized alphabetically in the name (methyl precedes propyl).

Hence the systematic name for the molecule (a) is (2S, 3R)-3-methyl-2-propylcyclopentanone.
