Question

The correct IUPAC name of the following alkane is ?

• A. 3,6-diethyl-2-methyloctane
• B. 5-iso-propyl-3-ethyloctane
• C. 5-ethyl-5-iso-propyloctane
• D. 3-iso-propyl-6-ethyloctane

Answer 1

Answer: (A)

3,6-diethyl-2-methyloctane

The IUPAC nomenclature is a system on which most organic chemists have agreed to provide guidlines to allow them to learn from each others works. Nomenclature, in other words, provides a foundation of language for organic Chemistry.

Alkanes with five or more carbon atoms are named by adding the suffix -$ane$ to the appropriate numerical multiplier, except the terminal $\alpha$ is removed from the basic nymerical term.

Hence IUPAC name for the given structure is 3,6- diethyl-2-methyloctane
