Give the IUPAC name for each of the following alkanes.

a.

b.

c.

d.

Interpretation:

IUPAC name for the given alkane has to be written.

Concept Introduction:

Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry).  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.

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

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

To name an alkane, the first step is to find the longest carbon chain.  The next step is to identify the substituents that are present in the longest carbon chain.  The numbering has to be given in a way that the substituents get the least numbering.

From the given structure the lengthy carbon chain has to be identified.  In this case it is a seven carbon chain and hence the parent alkane is heptane.

The substituents that are present in the longest carbon chain have to be identified.  It is found that two methyl groups and an ethyl group is substituted in the carbon chain.

Interpretation:

IUPAC name for the given alkane has to be written.
