Question:Give IUPAC name of each compound.

a. ${\left(C{H}_3\right)}_{\mathbf{3}}\mathbf{-}\mathit{C}{\mathit{H}}_{\mathbf{2}}\mathbf{-}\mathit{C}\mathit{H}\mathbf{-}{\left(C{H}_{2}C{H}_3\right)}_{\mathbf{2}}$

b.

c.$\mathit{C}{\mathit{H}}_{\mathbf{3}}{\left(C{H}_2\right)}_{\mathbf{3}}\mathit{C}\mathit{H}\left(C{H}_{2}C{H}_{2}C{H}_3\right)\mathit{C}\mathit{H}{\left(C{H}_3\right)}_{\mathbf{2}}$

d.

It is a method by which organic compounds are designated particular names based on their structure and substituents.IUPAC stands for the International Union of Pure and Applied Chemistry.

The bonds are named in the following manner:

• -ane foralkane
• -ene foralkene
• -yne foralkyne

The prefix is determined by assigning the lowest possible numbers, and the names of the substituents are listed based on numbering priority and alphabetical order.

a. The largest carbon chain is hexane. Here, the substituents are one ethyl and two methyl groups.

The position and the order of substituents give the name of the compound as4-ethyl-2,2-dimethylhexane.

b. The largest carbon chain is heptane. Here, the substituents are methyl and isopropyl groups.

The position and the order of substituents give the name of the compound as 3-isopropyl-5-methylheptane.

c. The largest carbon chain is octane. Here, the substituent is attached with the fourth carbon as the isopropyl group.

The position and the order of substituent give the name of the compound as 4-isopropyloctane.

d. The largest carbon chain is decane. Here, the substituents are two methyl, one ethyl, and one isobutyl group.

The position and the order of substituents give the name of the compound as 2,7-dimethyl-3-ethyl-5-isobutyldecane.
