What organic compound contains three elements?

Answer 1

Carbohdrates , alcohols , phenols , aldehydes , ketones , carboxylic acids , esters and ethers are common classes of organic compounds which contain carbon , hydrogen and oxygen only.

Ethanol

There are literally millions (and that's being extremely conservative) of organic compounds which contain three elements (even more, if you take the question as meaning "at least three" instead of "exactly three").

If you're just looking for an example of one that contains exactly three:

Carbohydrates are organic compounds that contain the three elements Hydrogen, Oxygen and Carbon in some combination.

Answer 2

many organic compounds have three elements, all carbohydrates, fats, fatty acids, and vegetables oils have carbon, hydrogen and oxygen. An organic compound of three atoms would be carbon dioxide.

Answer 3

Sodium hydroxide is made up of sodium, hydrogen and oxygen.

Calcium hydroxide is made up calcium, hydrogen and oxygen.

Calcium nitrate is made up of calcium, nitrogen and oxygen.

Calcium phosphate is made up of calcium, phosphorus and oxygen.

Ethanol is made up of carbon, hydrogen and oxygen.

Answer 4

An example of an organic compound containing three elements is ethanol. Ethanol is composed of carbon, hydrogen, and oxygen atoms.

Answer 5

There are many compounds only composed of carbon, hydrogen, and oxygen; too many to list.
