Question

question
identify the name of the carboxylic acid derived from alkane with six carbons.
select the correct answer below:
hexanic acid
hexanoic acid
pentanoic acid
hexanol

Explanation:

• Alkanes with six carbons are named hexane.
• For carboxylic acids, the naming rule is to change the -e of the corresponding alkane name to -oic acid. So hexane becomes hexanoic acid.
• Hexanic acid is not the correct IUPAC - approved name.
• Pentanoic acid is derived from pentane (a five - carbon alkane).
• Hexanol is an alcohol (the -ol suffix indicates an alcohol group, not a carboxylic acid group).

Answer:

hexanoic acid
