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.

Conclusion: (Identity‚ % error‚ other evidence‚ how to improve) The identity of Unknown A is the compound cobalt(II) chloride hexahydrate (CoCl₂•6H₂O).This is justified by the similarities in color of red-purple crystal like grains‚ which is significant in identifying the product out of the eight suggested identities. Only two had similar characteristics which were CoCl₂•6H₂O and CoSO₄•6H₂O. Before unknown A was heated‚ there was a notable common physical property of the substance being red crystal
