Which of the following are properties of hydrocarbons? (A) hydrophilic, good source of stored energy, nonpolar.(B) hydrophilic, polar, consisting primarily of carbon, hydrogen.(C) hydrophobic, containing many hydroxide groups, polar.(D) hydrophobic, nonpolar, good source of stored energy

Respuesta :

Answer: the correct answer is (D) hydrophobic, nonpolar, good source of stored energy,

Explanation:

Hydrophobic literally means the 'fear of water, . Hydrocarbons are compounds that are composed of hydrogen and carbon molecules. The hydrophobic effect is caused by the hydrocarbons tendency to repel water molecules. The molecular structure of hydrocarbons creates a cage that doesn't allow water to pass through them.

The molecules of hydrocarbons are nonpolar because the atoms in the molecules have similar electronegativities.

Hydrocarbons are organic molecules consisting entirely of carbon and hydrogen. They make good fuels because their covalent bonds store a large amount of energy, which is released when the molecules are burned ( for example, when they react with oxygen to form carbon dioxide and water).

The properties of hydrocarbons are: hydrophobic, nonpolar, good source of stored energy

Explanation:

  • Hydrocarbons are organic compounds made up of carbon and hydrogen atoms.
  • They are colorless
  • They odorless
  • They are water-repelling that is hydrophobic compounds.
  • They are nonpolar in nature, so soluble in nonpolar solvents
  • They are also a source of energy. When hydrocarbons are combusted they give out carbon dioxide, water, and heat as products.
  • There are two types of hydrocarbons saturated and unsaturated.
  • Saturated hydrocarbon has a single bonded carbon atom bond whereas in unsaturated hydrocarbons double or triple bonded carbon atoms are present.
  • For example, methane ([tex]CH_4[/tex]), ethene ([tex]C_2H_4[/tex]), benzene ([tex]C_6H_6[/tex]) ,etc.

So, from this, we conclude that the properties of hydrocarbons are: hydrophobic, nonpolar, good source of stored energy.
