Dehydration of liqors is useful since readily converted to an liqor to an alkene. A simple example is the synthesis of cyclohexene by dehydration of cyclohexanol. You can see the action of acid (H2SO4) sulfuric acid which removes the hydroxyl group of liqor, generating the double bond and water (alcohol assessment). The hydroxyl is replaced by a halogen in Appel reaction. Many liqors may be created by fermenting yeast fruit or grain, but only ethanol is produced commercially this way, mainly as a fuel and as a beverage. Other liqors are generally produced as synthetic derivatives of natural gas or oil.
The acidity of hydroxyl group is similar to that of water, although it depends mainly steric hindrance and the inductive effect. If a hydroxyl is bonded to a tertiary carbon, it is less acidic than if he were bound to a secondary carbon, and in turn it would be less acidic than if I was bound to a primary carbon, because steric hindrance prevents the molecule is effectively solvate. The inductive effect increases the acidity of liqor if the molecule has a large number of electronegative atoms attached to adjacent carbons (electronegative atoms help stabilize the negative charge of oxygen by electrostatic attraction).
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.
There is also a group sometimes regarded as a special case of liqors called enols. This is a molecule in which hydroxyl is attached to a carbon of a double bond C equals C (again carbon bearing the -OH group is not tetrahedral). This is actually a tautomeric form of an aldehyde or ketone. The major form is usually the aldehyde or ketone, and not the enol, except in special cases where the enol form is stabilized by mesomerism as phenols.
The fact that the hydroxyl group can also form hydrogen bonds affects the melting and boiling points of liqors. Although the hydrogen bond formed is very weak compared to other types of bonds are formed in large numbers between molecules, forming a collective network which hinders the molecules can escape the state in which they are (solid or liquid), thus increasing their melting and boiling points compared to corresponding alkanes. Furthermore, two points are usually far apart, so are often used as components of antifreeze mixtures. For example, 1,2-ethanediol has a melting point of -16 degrees C and a boiling point of 197 degrees C.
