Answer:
Fatty acid.
Explanation:
Hello,
In this case, based on the given formula, it is possible to infer that the O₂ at the end, accounts for the presence of a carboxyl group (first attached picture), characteristic of carboxylic acids. Moreover, long-chained carboxylic acids are considered as fatty acids due to their high nonpolarity and hydrophobicity, therefore, the molecule with such formula probably a fatty acid, more precisely, stearic acid (second attached picture).
Best regards.
