  2. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    In the fossil fuel industries, hydrocarbon refers to naturally occurring petroleum, natural gas and coal, or their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers.

  3. Water associated fraction - Wikipedia

    en.wikipedia.org/wiki/Water_associated_fraction

    The water associated fraction (WAF), sometimes termed the water-soluble fraction (W.S.F.), is the solution of low molecular mass hydrocarbons naturally released from petroleum hydrocarbon mixtures in contact with water. Although generally regarded as hydrophobic, many petroleum hydrocarbons are soluble in water to a limited

  4. Water - Wikipedia

    en.wikipedia.org/wiki/Water

    Water is also central to acid-base neutrality and enzyme function. An acid, a hydrogen ion (H +, that is, a proton) donor, can be neutralized by a base, a proton acceptor such as a hydroxide ion (OH −) to form water. Water is considered to be neutral, with a pH (the negative log of the hydrogen ion concentration) of 7 in an ideal state.

  5. Saturated and unsaturated compounds - Wikipedia

    en.wikipedia.org/wiki/Saturated_and_unsaturated...

    A saturated compound is a chemical compound (or ion) that resists addition reactions, such as hydrogenation, oxidative addition, and binding of a Lewis base.The term is used in many contexts and for many classes of chemical compounds.

  6. Outline of water - Wikipedia

    en.wikipedia.org/wiki/Outline_of_water

    Faucet dripping water. Structure of the water molecule (H 2 O) The following outline is provided as an overview of and topical guide to water: Water – chemical substance with the chemical formula H 2 O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds.

  7. Hydroxy group - Wikipedia

    en.wikipedia.org/wiki/Hydroxy_group

    Sulfuric acid contains two hydroxy groups.. Water, alcohols, carboxylic acids, and many other hydroxy-containing compounds can be readily deprotonated due to a large difference between the electronegativity of oxygen (3.5) and that of hydrogen (2.1).

  8. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Water (H 2 O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue.It is by far the most studied chemical compound [20] and is described as the "universal solvent" [21] and the "solvent of life". [22]

  9. Chemical bonding of water - Wikipedia

    en.wikipedia.org/wiki/Chemical_bonding_of_water

    Water (H 2 O ) is a simple triatomic bent molecule with C 2v molecular symmetry and bond angle of 104.5° between the central oxygen atom and the hydrogen atoms. Despite being one of the simplest triatomic molecules , its chemical bonding scheme is nonetheless complex as many of its bonding properties such as bond angle , ionization energy ...
