Give IUPAC names for the following alkanes, and convert each drawing

into a skeletal structure.

Short Answer

Expert verified

(a) The IUPAC name of the structure is 3-Ethyl-2-methylpentane.

Step by step solution

01

IUPAC nomenclature of alkanes

IUPAC nomenclature constitutes an important approach to provide name for several compounds. If two different chains comprising same length are present, then the chain comprising several branch points is selected as parent.

02

IUPAC name and skeletal structure of compound b

(b)The longest carbon chain of the compound has five carbon atoms and is named pentane. The second carbon atom has a methyl group and the third carbon atom has an ethyl group. The IUPAC name of the compound is 3-Ethyl-2-methylpentane. The skeletal structure can be given as:

Skeletal structure of compound b
