One such type is hydrocarbons, which contain only hydrogen and carbon with no oxygen at all.
lipids
which of these elements must be in organic compuonds oxygen hydrogen carbon helium or iron
Contains carbon. Technically, an organic compound is one which contains carbon bonded to hydrogen or oxygen. The major groups of organic compounds are proteins, lipids and carbohydrates.
No, it is not. It is a compound, not an element. RNA contains carbon, nitrogen, hydrogen, oxygen, and phosphorus.
Methylated spirit is Ethanol and Methanol Ethyl Alcohol and Methyl Alcohol Which are organic Ethanol contains Carbon , Oxygen and Hydrogen and methanol Contains Carbon , Oxygen and Hydrogen the both alcohols are chemical compounds
No because Oxygen is an element and it only contains atoms of Oxygen and nothing else, no Hydrogen at all. A compound of Hydrogen must contain Hydrogen plus something else. Water contains Hydrogen and Oxygen (H2O) so that would be a compound of Hydrogen and oxygen.
Vanillin is definitely a compound. It contains Carbon , hydrogen and oxygen. It has three functional groups, an aldehyde, hydroxyl, and an ether.

Lipid
hydrogen, carbon, oxygen
Carbohydrates :)
Any alcohol would contain these 3 elements.
An organic compound must contain carbon and hydrogen, but also may contain oxygen, nitrogen, sulfur, and phosphorus. An organic compound that contains only carbon and hydrogen is called a hydrocarbon.
No. Baking soda contains the elements sodium, hydrogen, carbon, and oxygen chemically combined, which makes it a compound. Its formula is NaHCO3. The scientific names of baking soda are sodium bicarbonate and sodium hydrogen carbonate.
Organic compounds are compounds containing carbon and hydrogen covalently bonded with one another.
Protein contains nitrogen, carbon, oxygen, and hydrogen
Contains carbon. Technically, an organic compound is one which contains carbon bonded to hydrogen or oxygen. The major groups of organic compounds are proteins, lipids and carbohydrates.
There are countless compounds composed of carbon, hydrogen, and oxygen.
