The -COOH is bonded to a long chain of hydrocarbons in a fatty acid.

A hydrocarbon chain is comprised of both carbon (C) and hydrogen (H) atoms. The 'acid' part is made up of the -COOH portion, whereas the 'fatty' part is made up of the long hydrocarbon chain that it is attached to.

Answer: Option (1) is the correct answer.

Explanation:

A chain of carbon and hydrogen atoms also known as hydrocarbons when attached to at least one carboxylic acid functional group (COOH) then it is known as a fatty acid.

For example, [tex]CH_{3}(CH_{2})_{10}COOH[/tex] is lauric acid and it is a saturated fat.

Whereas a hydrocabon that contain atleast one "-OH" functional group is known as an alcohol.

A hydrocabon that contain atleast one "-CHO" functional group is known as an aldehyde.

A hydrocabons that contain atleast one "O=C-O" functional group is known as an ester.

Thus, we can conclude that a fatty acid consists of -COOH bonded to a long chain of hydrocarbons.
