How do organic compounds differ from inorganic compounds? 1) all organic compounds contain carbon. 2) only organic compounds contain hydrogen. 3) organic compounds are natural, while inorganic compounds are synthetic. 4) organic compounds contain water, while inorganic compounds do not contain water.

All the organic compound differs from inorganic compound by carbon composition.

Option A

Explanation:

An organic compound is a compound which is composed of one carbon particles binded with different components. Most generally, these carbon molecules are clung to hydrogen, oxygen and nitrogen particles. On the other hand,  an inorganic compound is not basically made out of carbon molecules.

There can be either carbon atoms present or missing. Thus it can be inferred that the presence and absence of carbon determines whether a compound is inorganic or organic.
