Basic Overview Of Alcohol Assessment

By Stacey Burt


The liqors can act as acids or bases by which the functional group is similar to water, so that a dipole similar to having the water molecule is established. On one hand, if an liqor is faced with a strong base or an alkali metal hydride forms the alkoxy group, where the hydroxyl group is deprotonated leaving negatively charged oxygen (alcohol assessment).

Liqors have a wide range of uses in industry and science as solvents and fuels. Ethanol and methanol can be combusted in a cleaner than gasoline or diesel manner. By low toxicity and availability for non-polar substances dissolve, ethanol is often used as a solvent in pharmaceuticals, perfumes and flavorings such as vanilla vital. Liqors frequently serve as versatile intermediates in organic synthesis.

The Arabs knew the extracted wine distilled liqor. However, its discovery dates back to early fourteenth century, attributed to medical Arnau de Villanova, wise alchemist and professor of medicine at Montpellier. The quintessence of Ramon Llull was nothing that liqor grinding to a milder temperature.

Tertiary liqor: tertiary liqors react almost instantaneously, because they are relatively stable tertiary carbocations. Tertiary liqors react directly with hydrochloric acid to produce the tertiary chloroalkane, but a primary or secondary liqor is used the presence of a Lewis acid is required, a "trigger" as zinc chloride.

If it is not the main function, add the prefix hydroxy- preceded by the carbon atom number where the group is attached. For the conjugate base of liqor, liqorate ion, just replace the terminal vowel "e" by -olate suffix (not to be confused with the suffix -oate characteristic of carboxylate, conjugate base the carboxylic acid).

When liqor is substituent group, the hydroxy prefix is used. The diol, triol, etc. Suffixes are used, depending on the amount of OH groups. Monoliqors alkanes derivatives corresponding to general formula CnH2n plus 1OH. The liqors are typically colorless liquids with characteristic odor, soluble in water in varying proportions and less dense than it. By increasing the molecular weight, increase their melting and boiling points and may be solid at room temperature (ie the pentaerititrol melts at 260 degrees C). Unlike those derived alkanes, the hydroxyl functional group allows the molecule soluble in water due to similarity of hydroxyl group with the water molecule and allows hydrogen bonding.

Tertiary liqor: although resist being oxidized with mild oxidizing, if an energetic as potassium permanganate is used, tertiary liqors are oxidized products giving as a ketone with a number less carbon atoms, and methane is released .

The liqors can be produced by fermentation, including methanol from wood and ethanol from fruits and grains. The industry is resorted to only in case of ethanol to produce fuel and drinks. In other cases, liqors are synthesized from organic compounds from natural gas or oil in particular by hydration of alkenes.
