In 6/8 meter, the dotted quarter is considered the beat, and there are two of them in each measure. This is what makes 6/8 meter a compound duple meter; compound because its main beat can be divided into three parts, and duple because there are two main beats per measure:
Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials, and often have a characteristic pleasant, fruity odor.n chemistry, esters are chemical compounds derived from an acid (organic or inorganic) in which at least one-OH (hydroxyl) group is replaced by an-O- alkyl (alkoxy) group. Usually, esters are derived from a carboxylic acid and an alcohol.
Even then the reaction is an equilibrium and so does not go to completion. OOR H HOR' ROOR' H(+H) O + + For esters in which the alcohol and carboxylic acid are sterically unhindered, a 1:1 mixture of alcohol and carboxylic acid will yield an equilibrium mixture that is about 70% ester.his is also an application of Le Chatelierâs principle. Note that one product of the esterification reaction is water. A simple experimental set-up can be used to remove the water from the reaction mixture as the water, and ester, form.
