what carboxylic acid and alcohol make ethyl butyrate?

This is an esterification, \nButanoic Acid (CH3CH2CH2CO2H)+ ethanol (HO-CH2CH3), in basic media, yields ethyl butyrate. \n\nCH3CH2CH2CO2H + HO-CH2CH3 --> CH3CH2CH2COO-CH2CH3

Propyl isobutyrate, by which I assume you mean n-propyl iso-butyrate, has many common names including:\n\nPropanoic acid, 2-methyl-, propyl ester; Isobutyric acid, propyl ester; Propyl isobutyrate; Isobutyric acid n-propyl ester; n-Propyl 2-methylpropanoate; Propyl 2-methylpropanoate; Propyl isobutanoate\n\nThe NIST chemistry webbook has all of this stuff online for free.

With a little acid present as catalyst, the product is acetone plus methanol. The first product is 2-propenol, but that tautomerizes at once to acetone.

If you write your ester like this, C2H5COOH, it is not an ester, but a carboxylic acid.\n\nIf you write it as, CH3C00CH3, then it is the ester methyl ethanoate that is made of ethanoic acid and methanol.\n\nIf you write it as, HCOOC2H5, then it is the ester ethyl methanoate that is made of methanoic acid and ethanol.

2-hexanol. Look at the link, I think this is what you want.

Well use a series of steps.\n\n1st step add Calcium Carbonate. This will fizz in the case of the vinegar, as acid plus carbonate gives salt, water and carbon dioxide. U can even test the gas to be CO2, as it turns lime water milky. U will eliminate the vinegar from further tests.\n\n2nd is separate the alcohol from the salt and fresh water. Do this by testing with Cobalt chloride paper. The paper changes from blue to pink if any water is present. The sample which doesn't change the paper would be the alcohol.\n\n3rd is to separate the salt water from the fresh water. Do this by adding silver nitrate followed by aqueous ammonia. Salt contains sodium chloride, so the presence of the Cl- ion will cause the formation of a white precipitate that dissolves in excess alkali.\nSo, the one that produces no ppt is therefore pure water.

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.

The density of alcohol (ethyl) is 0.789 g/mL, so it would take up more space (less dense).  Water is 1 g/mL

No, carboxylic acid is NOT a kind of ester.\n\nBut, you can make ester using carboxylic acid.\n\nCarboxylic acid + alcohol = Ester + water\nEg:\nEthanoic acid + Propanol = Propil etanoate + Water\nCH3COOH + C3H7OH = CH3COOCH3H7 + H2O    \n\nEster formula: RCOOR'\nR => represents the hydrocarbon part of the carboxylic acid. \nIn the example given above, R = CH3COO\n\nR' => represents the hydrocarbon part of the alcohol. \nIn the example given above, R' = C3H7\n\nThis shows that carboxylic acid is NOT a kind of ester. Carboxylic acid is a homologue series. (Its members: Methanoic acid, ethanoic acid, propanoic acid, butanoic acid, etc)\n\nEster is a different homologue series. (It has many members, among them: Metil etanoate, etil etanoate, propil etanoate, metil metanoate, etil metanoate, butil pentanoate, and etc)\n\nQuote: "But I wonder the structure of acid fits that of ester and would like to know what make two so different."\n\nCarboxylic acid has the caboxylic functional group (COOH), whereas ester has the carboxylate bond as the functional group (COO).\n\n\nP.S. I learnt chemistry in Malay (I'm Malaysian!). So, forgive me if I misspelt any of the chemical terms.

Yes it's fine, they both kill bacteria.\n\nhttp://en.wikipedia.org/wiki/Ethyl_alcohol#Other_uses

The alcohol (ethyl alcohol) doesn't break down into nothing during digestion. Actually the only thing that alcohol turns into, during a long period of time touhgh, is vinegar (acetic acid).\nIt doesn't sit in your sistem, it is mainly eliminated trough breathing.

Ethanol is ethyl alcohol, the pharmacologically active part of beer.  It depends on the "proof" of the alcohol.  Pure alcohol is generally not "edible" (or drinkable) because ethanol forms an azeotrope (a mixture that cannot be separated by distillation) when it is ~95% ethanol and 5% water.  The azeotrope is broken by chemicals that are bad for humans, like benzene.
