Question

Write the condensed formula of the sixth member of the alkane family compound to predict its IUPAC name.

Answer 1

Definition for alkanes

• These are saturated hydrocarbons.
• They contain single-bonded carbon and hydrogen atoms.
• Subdivided into three groups: chain alkanes, cycloalkanes, and branched alkanes.
• The general formula for these types of hydrocarbon is ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2}$

Name	Formula (${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2}$)	Number of Structural Isomers
Hexane	${\mathrm{C}}_6{\mathrm{H}}_{14}$	5

Definition of IUPAC name

IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry.

Therefore the condensed formula for the sixth member of the alkane family : ${\mathrm{C}}_6{\mathrm{H}}_{14}$

And IUPAC name: n-Hexane
