Question

Compounds which contains only carbon and hydrogen are termed as:
(A) Hydrocarbons
(B) Organic compounds
(C) Inorganic compounds
(D) Carbohydrogens

Answer 1

Hint:In the given question firstly we have to define the kind of the compounds that are formed when the carbons and hydrogens combine. Now after this we get that the compounds that are made have the name of hydrocarbons which in case is made up of the naming using, Hydrogen + Carbon

Complete answer:The given question statement asks about the structure of the compound of calcium oxide, the integrative structure of the elements as a self and in the compound as a molecule.
Organic compounds contain only carbon and hydrogen are called hydrocarbons. In these compounds, all valencies of the carbon atom are satisfied by carbon or hydrogen only.
In the field of organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group hydrides. Hydrocarbons or the compounds from which one hydrogen atom has been removed are functional groups called hydrocarbons. Talking about the physical aspect the hydrocarbons are generally colourless and hydrophobic with only weak odours. Because of their diverse molecular structures, it is difficult to generalize further. Most anthropogenic emissions of hydrocarbons are from the burning of fossil fuels including fuel production and combustion. Natural sources of hydrocarbons such as ethylene, isoprene, and monoterpenes come from the emissions of vegetation.

Note:The predominant use of hydrocarbons is as a combustible fuel source. Methane is the predominant component of natural gas. The C6 through C10 alkanes, alkenes and isomeric cycloalkanes are the top components of gasoline, naphtha, jet fuel and specialized industrial solvent mixtures. With the progressive addition of carbon units, the simple non-ring structured hydrocarbons have higher viscosities, lubricating indices, boiling points, solidification temperatures, and deeper color.
