GENERAL KNOWLEDGE

Detailed explanation-1: -A hydrocarbon is any of a class of organic chemicals made up of only the elements carbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations. Learn more about chemical compounds.

Detailed explanation-2: -Hydrocarbons are a class of chemicals that contain only hydrogen and carbon atoms. Some have hydrogen with rings of carbon atoms, called polycyclic aromatic hydrocarbons or PAHs. Hydrocarbons with additives, such as gasoline, also are included.

Detailed explanation-3: -Organic compounds composed of only carbon and hydrogen are called hydrocarbons.

Detailed explanation-4: -Carbohydrates and hydrocarbons are two different classes of organic compounds. Though the names appear to be similar, there is a vast difference in their basic chemical composition. Carbohydrates contain Carbon (C), Hydrogen (H), Oxygen (O). Whereas hydrocarbons contain only Carbon (C) and Hydrogen (H).

Detailed explanation-5: -Hydrocarbons are compounds comprised exclusively of carbon and hydrogen and they are by far the dominant components of crude oil, processed petroleum hydrocarbons (gasoline, diesel, kerosene, fuel oil, and lubricating oil), coal tar, creosote, dyestuff, and pyrolysis waste products.
