Purpose:
Studied several aspects related to the reactions of carbon compounds such as addition reactions, esterification, redox, polymerization, and yodoform.
Theory:
Chemical reactions on carbon compounds can be classified into several types, including an addition reaction, esterification, polymerization, yodoform, redox reactions, substitution and elimination reactions. At this trial will be observed on addition reactions, polymerization, esterification, redox, and wherein each yodoform each has a characteristic reaction. Addition reaction is a coupling reaction of a compound with a specific reagent that accompanied changes in the bonding of these compounds as a double triple bond could be two or even a single double bond. Polymerization reaction is a reaction in which the chain extension unit that will polymerize compounds called monomers and the result is called a polymer composed of these monomers. esterification reaction is a reaction in which an ester bond formation in this experiment were made from alcohols and esters of carboxylic acids using an acid catalyst. merupakanreaksi redox reaction between two substances where one substance is reduced and oxidised, usually accompanied by changes in the conditions solution as a precipitate, color change, change in pH, viscosity changes and others. reaction yodoform is haloform reaction or making halaform compounds. To yodoform means CHl3 compounds will be generated.
