The word is "extract".\n\nAlcohol containing products such as wine, champagne, whiskey, beer etc are made from food products having a lot of carbohydrates like rice, wheat, barley etc. What differs in the wine, whiskey etc. is the amount of alcohol or more precisely Ethanol or C2H5OH, it is obtained on fermentation which breaks up the long starch chains into simpler ethanol molecules.\n\nFermentation is an oxidation reaction, if allowed to continue, C2H5OH is oxidised to Acetic or Ethanoic acid CH3COOH whose diluted form is vinegar.

Ethers can be prepared in the laboratory in several ways.\n\nDehydration of alcohols: \nR-OH + R-OH → R-O-R + H2O \nThis direct reaction requires drastic conditions (heat and an acid catalyst) and is usually not applicable. Such conditions can destroy the delicate structures of some functional groups. There exist several milder methods to produce ethers. \nNucleophilic displacement of alkyl halides by alkoxides \nR-O- + R-X → R-O-R + X- \nThis reaction is called the Williamson ether synthesis. It involves treatment of a parent alcohol with a strong base to form the alkoxide anion followed by addition of an appropriate aliphatic compound bearing a suitable leaving group (R-X). Suitable leaving groups (X) include iodide, bromide, or sulfonates. This method does not work if R is aromatic like in bromobenzene. Likewise, this method only gives the best yields for primary carbons, as secondary carbons will undergo E2 elimination on exposure to the basic alkoxide anion used in the reaction. Aryl ethers can be prepared in the Ullmann condensation. \nElectrophilic addition of alcohols to alkenes. \nR2C=CR2 + R-OH → R2CH-C(-O-R)-R2 \nAcid catalysis is required for this reaction. Tetrahydropyranyl ethers are used as protective groups for alcohols.

Generally, Grignard reactions are terminated by dumping the reaction mixture in water.   Any  phenylmagnesium bromide unreacted at that time (or other Grignard reagent) will react with the water.  phenylmagnesium bromide reacts with water to give benzene.  This is because the Grignard reagent acts as a base while the water acts as an acid.  Other protic solvents such as methanol will have an analagous reaction.

There are thousands of alcohols, its a class of organic compounds(made of carbon chains). All alcohols have a hydroxyl group attached somewhere on the carbon chain.\nThe general formula for alcohols is R-OH, where R is the carbon chain.

It looks like an alcohol.  An alcohol has the structure R-O-H, where R is any alkyl (carbon and hydrogen) group.

Alcohol is attracted to cell membranes, and it concentrates there. When it reaches nerve cell membranes, the alcohol can change the function of nerve cells and thus affect behavior.At one time, scientists believed that alcohol "dissolved" into the membrane interior and made the carbon chains of the lipids more fluid. (It was thought to be like converting hard butter into soft margarine.) \n\nWhen scientists tested this idea on fish, they realized that the "melted butter" idea could not explain intoxication. Warming fish by a few degrees can cause the same degree of lipid "melting", but t\nhe fish do NOT get intoxicated. The answer can be answered in part from the chemistry of alcohol (CH3CHOH). The carbon part of the molecule makes it attracted to the carbon tails of the lipids in cell membranes. But the OH group of alcohol makes it attracted to water. \n\nThus, you might expect that these influences would cause alcohol to orient itself in a membrane so that the carbon part of the molecule inserts itself into the membrane interior (where the lipid carbon tails are) and the OH part of the molecule is out near the surface, where the water is. This idea has been recently confirmed by the author of Cells Are Us and his colleagues here at Texas A&M.lcohol disrupts the normal organization of the lipid carbon chains (see picture below.)   \n\nYour scientist/author of this module believes that alcohol sticks to a membrane near its surface with water. Some of the evidence that supports this idea was obtained with a simple artificial lipid membrane. Several methods demonstrate that alcohol binds just underneath the charged head group of surface lipid, displacing some of the water that is normally there. The importance of this physical disruption is not so much what it does to the lipid, but what it does to the proteins (not shown) that are embedded in the lipid. Disturbing the shape of the lipids changes the shape of the proteins, and thus changes the functions of the protein.Think about how the substitution of alcohol for water might affect the large, complex sugars and proteins that are embedded in the lipid membrane. Ask yourself:\n\nWouldn't the substitution cause proteins to change shape? \n\nIf they changed shape, could that cause them to change function? \nAlthough the lipid of a membrane has no special function of its own, it does influence the large functional molecules (proteins and sugars) that the membrane contains. This is not a good thing.\n\nChanging a protein's shape or location can change the protein's function. Some membrane proteins are affected more by alcohol than are other proteins.

the production of alcohol is an anoxic reaction, if oxygen is present alcohol isn't produced. This is usually achieved by putting the fermentation mixture in a sealed flask with a water stopper in the top, this allows the escape of CO2 produced in the fermentation but doesn't allow O2 in the air to dissolve in the water

Alcohols would be the product of the reduction of aldehydes or ketones.  To get isoproanol, you would have to reduce acetone with either lithium aluminum hydride or sodium borohydride.\n\n(CH3)2C=O  --->  (CH3)2CH-OH

alcohols have a hydroxyl group, which the oxygen atom is electronegative and induces polarisation to the O-H bond, that means the oxygen atom is negatively changed and the hydrogen atom is positively charged (in the hydroxyl group). So that hydrogen atom in the hydroxyl group attracts to other negatively charged oxygen atoms on another molecule, so the 2 are held together by what is called hydrogen bonding\n\nalkane molecules only hold on together by Van der Waals forces, which is weak, whereas alcohols hold on together by hydrogen bonding and Van der Waals forces, which is a lot stronger\n\nso with stronger intermolecular forces, molecules hold on to each other stronger and therefore results as a higher boiling and melting point

I think it has to do with the fact that there is a benzene ring on it. The pKa of benzene is around 7 or 8, I believe. So benzene could have a n affect on the level of its acidity. \n\nIt could possibly be harder for a base to pick up a proton off the alcohol on the phenol than on the alcohol on a regular carbon chain, or ring with no double bonds. \n\nbut I'm just guessing.

E1 reactions proceed through carbonium ions. Carbonium ions resulting from particular carbon skeletons/derivatives are unique. Once the carbonium ion forms, it has a characteristic tendency to eliminate to an olefin, or to hydrate or solvate to an alcohol or an ether. So you can't control how much olefin, alcohol, or ether you'll get.\n\nOn the other hand, if the substrate is really cheap, like cyclohexanol, then an E1 reaction is the way to go, because you'll get cheap cyclohexene regardless of what ever else you have to put up with.

Alcohols can be prepared by adding water to an alkene in the presence of a strong acid such as concentrated sulfuric acid. This reaction involves adding an H2O molecule across a C=C double bond. Because these reactions follow Markovnikov's rule, the product of the reaction is often a highly substituted 2 or 3 alcohol.
