Question
Identify the pair of organic compounds from the following?
- Calcium bicarbonate
- Copper carbonate
- Carbon monoxide
- Benzene
Hint:
A large class of compounds having carbon as its primary element forming covalent bonds with hydrogen and other elements are known as organic compounds.
The correct answer is: Benzene
- Benzene is cyclic compound of 6 carbons forming covalent bonds with each other and 6 hydrogens (C₆H₆).
- Carbon monoxide is a compound consisting of carbon and oxygen(CO) and not a hydrocarbon that is why it is not classified as a organic compound.
- Calcium bicarbonate is a compound primarily of Ca cation and HCO3 anion, carbon is not the primary element.
- Copper Carbonate is also a salt and not a hydrocarbon.
