Question

A long chain of hydrocarbon bonded to cooh is a ________ acid.

a.formic
b.carbonic
c.amino
d.fatty

Answer 1

A long chain of hydrocarbon bonded to COOH is a FATTY acid.

Answer 2

Answer: Option (d) is the correct answer.

Step-by-step explanation:

A fatty acid is defined as a long chain of hydrocarbons that consists of a carboxylic group, that is, COOH group at the end of the chain.

General formula of a fatty acid is
`R-(CH_(2))_(n)-COOH` where n is mostly an even number in many cases.

Fatty acids are also known as aliphatic monocarboxylic acid.

For example,
`C_(17)H_(35)COOH` is the formula of stearic acid which is a fatty acid.

Thus, we can conclude that a long chain of hydrocarbon bonded to cooh is a fatty acid.
