Esters are chemical compounds derived by reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol
oxoacid is an acid that contains oxygen.
hydroxyl compound is simply an oxygen atom covalently bonded to a hydrogen atom.
----------example: water. In the case of ester, alcohol and phenol are examples.
covalent bonds are a bond between two atoms that share electrons.
alcohol is a hydroxyl compound bonded to carbon atom.
phenol is a hydroxyl compound bonded to a aromatic hydrocarbon group
aromatic hydrocarbon group is a group of alternating single a double bonded carbon.
--------example: C-C=C-C=C-C=C. Where (-) is asingle bond, and (=) is a double. This group is usually a ring.
So, react a oxoacid with a hydroxyl compound( alcohol or phenol to create in particular, ester) and you create a ester.
Esters are ubiquitous. Most naturally occurring fats and oils are the fatty acid esters of glycerol.
ubiquitous - found everywhere.
fatty acids are, what you need to know about them, high energy (ATP) compounds.
glycerol is a hydroxyl compound. react it with am oxoacid, and you create fatty acid esters.
Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group
I'm not sure on this part.
carboxyl acids are organic acids, and inorganic acids are not organic acid. Carboxyl acid seems to be the most common acid esters use, I think becuase it contains a hydroxyl group also. Since it contains both the oxoacid and the hydroxyl group, all you need is the dilute alkali to create the ester. From my understanding the difference in inorganic and organic is whether they contain carbon or not. organic contains carbon, inorganic does not. BUT, in some cases organic and inorganic are found bonded together.
it says MOST naturally occuring, which to me implies that there are some fats that are not esters. but quite alot of them are esters. non-natural fats are likely NOT esters, and there are likely a FEW natural fats that are not esters.
Does anyone know what happens if an ester (assuming there are many different ones, but I have no idea at all) and sodium hydroxide solution are put together?
To create an ester, you need an oxoacid and a hydroxyl compound(alcohol or phenol) inside a base. This base is water, dilute acid, or dilute alkali. The most common base is dilute alkali when creating ester. Sodium hydroxide is a dilute alkali. So you get a dilute alkali, throw in some oxoacid and hydroxyl compounds and you will then have esters in the dilute alkali.
Dilute means to make weaker. diluting an acid would raise the pH, diluting a alkali would lower the pH. water is considered neutral( pH 7.0).
Anyone who is more knowledgeable of chemistry please correct the mistakes. I'm having to learn this as I teach it lol. But at least now I know how to make ester...
