EXPERIMENT 1: TITLE: ISOMERISM AND KINETICS IN COORDINATION CHEMISTRY OBJECTIVE: 1. To prepare and study the kinetics of the interconversion of some of the isomers of a typical coordination compound. INTRODUCTION: Isomerism played a central role to establish the basic concept in coordination chemistry while reaction kinetics of coordination compound is known as the area of continuing intense research activity. The mechanism of the reactions of coordination compounds relevance

Exp.11) Identification of unknown ketones. Introduction: Given five samples of a known ketone derivative‚ the purpose of this experiment is to identify which unknown ketone derivative corresponds to the five known samples. In other words‚ using specific methods of compound detection‚ it is possible to match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment‚ identification of the unknown ketone is accomplished through thin

Ronak Parikh U30682934 Experiment 2: Diels-Alder Reaction: Synthesis of cis-Norbornene-5‚6-endo-dicaroboxylic anhydride Introduction: The main goal of this experiment is to perform a Diels-Alder reaction between 2‚3-dimethyl-1‚3-butadiene and maleic anhydride‚ identify the product and hydrolyze to form the dicarboxylic acid. Diels alder reactions are classified as pericyclic reaction‚ which is a reaction which involves a cyclic rearrangement of bonding electrons‚ which means

to build the models. There are many organic substances that have identical molecular formulas but are completely different compounds. Consider the molecular formula C2H6O. There are two compounds that correspond to this formula: ethyl alcohol and dimethyl ether. While the molecular formula gives no clue as to which compound one may be referring‚ examination of the structural formula immediately reveals a different arrangement of atoms for these substances. Compounds that have the same molecular formula

Methanol were added in residue for sequential extraction. Solvents; Hexane‚ Chloroform‚ Acetone and Methanol were evaporated by placing the extracts in fume hood for 7-10 days. Stock solution prepration: To prepare 40 µg/µl stock concentration in Dimethyl sulfoxide (DMSO)‚ 40mg of each plant extract was suspended in DMSO‚ inside Laminar flow hood. Stock solutions were filtered through 0.22 µm filter and then stored at -20ᵒC.
