Question

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

into a skeletal structure.

Step-by-Step Solution

Answer

(c) The IUPAC name of the structure is 2,2,4-Trimethylpentane.

Step 1: IUPAC nomenclature

Alkanes comprise a name ending with ‘ane’. Those comprising unbranched carbon chain are provided name according to the count of carbons in them.

Step 2: IUPAC name and skeletal structure of compound c

(c)The longest carbon chain comprises five carbon atoms and is named pentane. The second carbon comprises two methyl groups and the fourth carbon atom has one methyl group. The IUPAC name of the compound is 2,2,4-Trimethylpentane. The skeletal structure can be given as:
