Classification Tests for Carboxylic Acid and Derivatives Mary Catherine Sarte‚ John Emmanuel Sy‚ Allurie Umel‚Franklin Yap‚ Mary Christine YouIntroduction Carboxylic acids derivatives are simply groupsof compounds that contain a carbonyl group butwith an electronegative atom attached to thecarbon. The difference in the structure leads to amajor change in reactivity. The reactions of thesegroups of compounds involve nucleophilicsubstitution. Although there are abundant kindsof carboxylic acid derivatives

Amino acids are a highly important class of molecules‚ which are the monomeric subunits of proteins‚ enzymes‚ and peptides in biological systems. Amino acids contain a carboxylic acid group‚ an amine group‚ and a unique side chain‚ which determines its properties. There are more than 500 amino acids; however‚ only 20 are commonly found1. Due to their importance in biological systems‚ it is important to be able to experimentally analyze and isolate amino acids by separation techniques. One such method

* Introduction to Organic Chemistry Understand the basis of drawing organic structures Depicting 3-D structures in 2-D Most organic compounds have a three-dimensional structure. How do we represent structures on our two-dimensional page? For example‚ methane is a tetrahedral molecule: Bonds in the plane of the paper: Bonds coming towards the observer: (out of the page) Bonds going away

Premium Carboxylic acid Alcohol Amine
There are many different binding modes of ligands to transition metal atoms. In past experiments with Co(II) and Co(III)‚ you observed that a ligand such as Chloride or amine can coordinate in a monodentate fashion. You also observed that carbonate occupies two sites of a transition metal and is known as a bidentate ligand. In this experiment‚ you will observe the reaction of a -bond in an olefin with a molybdenum metal center to form a piano-stool shaped molecule. The molybdenum metal retains
