General Features of Oxidative Additions Oxidative addition reactions usually involve a coordinatively unsaturated 16-electron metal complex or five-coordinate 18-electron species‚ and take the general from: [pic] If the A and B ligands in the product are considered to be formally –1‚ then the metal center has increased its oxidation state by +2‚ and this is the origin of the name oxidative addition. Oxidative reaction can occur when a metal complex

CHAPTER I INTRODUCTION Pollution is one of the main problems the world faces today. One of the reasons is the overload of non-biodegradable objects like plastics‚ cans and Styrofoam. The invention of plastics and Styrofoam made a huge change in our society and it helped us in many ways. But it is also one of the main pollutants that destroy our planet. Because of these we devised a way to recycle used Styrofoam‚ and this is to make glue out of it. This glue can help reduce the number of Styrofoam

Polyphenols (also sometimes termed ‘phenolics’)‚ are benzene rings which is a class of chemical compounds that consists of a hydroxyl (-OH) group‚ which is directly bonded to an aromatic hydrocarbon group. Phenolic compounds are widely produced industrially however; they are also produced by plants (mainly for protection against stress) and microorganisms where variations occur between different species. Polyphenols play vital roles in the growth of plants‚ especially in lignin and pigment biosynthesis

displayed formula for the 4-aminobenzenecarboxylic acid compound is shown and it shows the formula in a ring form therefore means that the compound is an aromatic compound. This is an aromatic compound because the compound consists of six carbons of benzene joined in a ring‚ having the planar geometry of a regular hexagon in which the distance between all of the C-C bonds are equal. The compound has three different isomers that are separated out and those are 2-aminobenzenecarboxylic acid and the structural
