Question

By using the general formula for alkanes write the formula of its sixth member.

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 ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2}$

Therefore, the formula of its sixth member of the alkane family:

Name	Formula (${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2}$)
Hexane	${\mathrm{C}}_6{\mathrm{H}}_{14}$
