Consider the following condensed formula of alkane: (CH3)2CH(CH2)-C(CH3)3 The correct name of the above formula according to IUPAC is:
Correct answer: D. 2,2,4-Trimethylpentane
- A. 2,3,4-Trimethylpentane
- B. 2,6,6-Trimethylpentane
- C. 2,4,4-Trimethylpentane
- D. 2,2,4-Trimethylpentane
Explanation
According to this name, there are three methyl groups attached to carbon atoms, two on 2nd carbon atom and one on 4th carbon atom of the pentane chain. This name correctly represents the structure given in the condensed formula. Therefore, the correct IUPAC name for the given condensed formula (CH3)2CH(CH2)-C(CH3)3 is 2,2,4-trimethylpentane (option D).

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
