Being able to extract a compound or substance from a product or object will encourage us in being able to do the same in a similar manner with a tea solution. Extracting compounds is an important step in any kind of organic chemistry lab and will help us be better at accomplishing the experiment in a much faster and accurate rate than from before. Experimental To begin the experiment‚ a tea solution must be made by incorporating a tea bag into a beaker filled with almost boiling water and the

Esterification Lab Introduction Esterification is an important part of organic chemistry that has many practical applications. Esterification can be used to make polymers. In most cases‚ esters are used for scents – they often smell fruity and sweet. In general‚ an esterification reaction results from a condensation reaction between a carboxylic acid and an alcohol. The carboxylic acid group loses an OH group‚ and the alcohol loses and H. For instance‚ the reaction between methanoic acid and methanol

Post-Lab Report for Experiment 2: Cooperative Identification of an organic Solid October 6‚ 2013 Introduction: This experiment was focused on the cooperative identification of organic compound by its chemical properties such as: slow melting point‚ mixed melting point‚ Rf values in TLC experiment‚ IR spectrum analysis‚ and H NMR spectra. Such data can provide the the identity of functional groups and the identity of the compound itself. In this experiment
