Which two elements do all organic compounds contain?
A
Carbon and hydrogen
B
Carbon and oxygen
C
Oxygen and hydrogen
D
Carbon and nitrogen
Explanation: 

Detailed explanation-1: -Organic molecules are molecules that are made of carbon and hydrogen, and can include other elements. Organic molecules must contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds). They usually involve oxygen and can also contain nitrogen, sulfur, phosphorous, and others.

Detailed explanation-2: -Organic compounds composed of only carbon and hydrogen are called hydrocarbons.

Detailed explanation-3: -This means that all organic compounds have in common the presence of carbon atoms and hydrogen atoms. In addition, different organic compounds may contain oxygen, nitrogen, phosphorous, and other elements.

Detailed explanation-4: -Hydrocarbons are organic molecules consisting entirely of carbon and hydrogen. We often use hydrocarbons in our daily lives: for instance, the propane in a gas grill and the butane in a lighter are both hydrocarbons.

Detailed explanation-5: -organic molecules ALWAYS contain carbon and hydrogen and are typically structurally complex!
