Preparation of Esters Introduction Esters are known for their pleasant smells such as perfumes and artificial flavorings in contained labs. They are formed when a carboxylic acid reacts with alcohol and a strong acid such as a catalyst called sulfuric acid (H2SO4) for this lab. The structural formula for esters can be represented as R-COO-R’. The R and R’ symbolizes different alkyl groups that can be combined to the ester. When naming an ester the first part comes from the alcohol followed

Alkenes from Alcohols: Analysis of a Mixture by Gas Chromatography Aim: To analyze a mixture of alkenes by gas chromatography. Introduction: In this lab‚ we specifically used elimination reaction; however we only used the E1 reaction. In the presence of strong acids‚ alcohols protonate to form a good leaving group‚ namely water. Upon loss of a proton to a good leaving group‚ an introduction of unsaturation (a double bond) can be preformed. According to Wikipedia‚ an E2 reaction is typically
