Organic compounds are _?
Correct answer: D. Non-polar
- A. Inorganic
- B. Polar
- C. Ionic
- D. Non-polar
Explanation
The electronegativity of carbon is 2.55 and of hydrogen is 2.2, the difference between them is 0.33. If the difference of electronegativities is less than 0.5, then the compound/bond is "non-polar". Hence, hydrocarbons are "non-polar".

About Classification of Organic Compounds
Organic compounds are classified by carbon skeleton into open-chain, branched-chain and cyclic compounds, including homocyclic and heterocyclic types. The classification also uses functional groups to distinguish hydrocarbons, halo compounds, alcohols, aldehydes, ketones, carboxylic acids and their derivatives, which is different from naming compounds by IUPAC rules.
