### acid:

Phenol
* Some phenols are sold as dietary supplements
  - have antiseptic properties, while others disrupt endocrine activity
  - occur naturally in the environment.
  * is produced from petroleum. It is an important molecule because it can be used to make many other products. It is also used in detergents and herbicides
* affects the central nervous system, liver, and kidneys.
* also give a negative test.
* are acidic due to the dissociability of their -OH group
  - antiseptic and kill bacteria and viruses and are found in oregano and thyme oil
  - caustic, poisonous, acidic compounds
  - chemical compounds
  - coal-tar derivatives
  - found in the natural world, especially in the plant kingdom
  - hardest to get rid of, because they are more difficult to decompose
  - organic compounds
  - simple molecules, made of a few oxygen and hydrogen atoms
  - the blue, blue-red and violet colorations seen in berries, grapes and purple eggplant
  - very good at killing gram positive bacteria
  - weak acids which are widely used for their antiseptic and disinfectant properties
* can also cause severe damage to eyes, including blindness
  - reactions including convulsions, coma, and circulatory collapse
  - catch on fire
  - do electrophilic aromatic substitution reactions very well
  - have positive effects when used for medical reasons
  - penetrate leather on shoes or clothing
* carbolic acid and reacts highly acidic and works like a strong cell poison.
* causes nerve destruction by inducing protein precipitation
  - severe burns when it comes in contact with skin
* chemically interact with many other substances.
* combustible liquid.
* compounds Some phenol compounds are also available.
* constitutes one of the main pollutants to be removed from wastewater.
* denatures proteins.
* extract extensively.
* give a brown color or precipitate as a positive test.
* helps lower the risk by preventing fat-like substances from oxidizing and clogging arteries.
* highly effective disinfectant and anesthetic for the skin.
* is absorbed easily into the body through the skin, lungs, and stomach
* is also a powerful disinfectant and bacteria killer
  - recoverable byproduct of coal pyrolysis
  - flammable
  - harmful
* is an agent that injures the local nerve it has been injected close to
  - colorless when solved in water but presents a characteristic sweet tar like odor
  - considered to be the parent chain
  - corrosive to the skin and mucous membranes
  - derived from the distillation of coal tar, creosote from the distillation of wood
  - found naturally in decaying dead organic matter like rotting vegetables and in coal
  - good sclerosant
* is highly corrosive and can be absorbed through skin
  - toxic and highly combustible
  - less acidic than the other molecule
  - reduced to benzene when it is distilled with zinc dust
  - regarded as a substance with good warning properties
  - so inexpensive that it attracts many small-scale uses
* is the deepest peel
  - prime ingredient in Epoxy
  - strongest of the chemical solutions and produces a deep peel
  - transported as a solid or in gel form
  - very soluble in water and is quite flammable
* monoprotic acid.
* often have chiral centers.
* peels, for example, can alter the color of the skin and permanently make it lighter.
* produced by high temperature fermentation are also to be avoided.
* therefore exists essentially entirely in the enol form.
* turns red on exposure to sunlight and air because of oxidation.
* weak acid material and corosive.
+ Phenol, Properties, Reactions: Organic compounds
  * Phenol can do electrophilic aromatic substitution reactions very well. This is because the lone pair on the oxygen atom can give electrons through the benzene ring to an electrophile. Because the lone pair is so high in energy however, sometimes phenol reacts too many times.
