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.
exothermic reaction-a chemical reaction accompanied by the evolution of heat. hydrolysis-a chemical reaction in which water reacts with a compound to produce other compounds; involves the splitting of a bond and the addition of the hydrogen cation and the hydroxide anion from the water.ddition reaction-a chemical reaction in which one molecule is added to another. aldol reaction-a reaction of aldehydes resulting in an aldol. chain reaction-a series of chemical reactions in which the product of one is a reactant in the next.
