    Comparing the enthalpy changes of combustion of different alcohols Aim In this experiment I will investigate the enthalpy changes of combustion. In particular I will be investigating the enthalpy change of combustion for different alcohols. I hope to investigate some of the homologous series alcohols‚ as well as a few structural isomers of these alcohols. Background & theory Enthalpy cannot be measured. What we can actually measure is the enthalpy change from the reactants to the products.

    the substitution of a proton with a functional group. The electrophilic aromatic substitution reaction nitration is used to nitrate methyl benzoate and acetanilide with a nitronium ion. Crystallization was used to purify the product. The melting point was used to determine its purity and the regiochemistry of the products. The methyl benzoate reaction product‚ methyl nitrobenzoate‚ was determined to be meta-substituted and the acetanilide reaction product‚ nitroacetanilide‚ was determined to be para-substituted

    Solubility as a Property of Matter A Lab of Chemicals‚ Chromatography‚ and Crime! Chemistry is a natural science that deals with the composition of matter and the changes it undergoes. At crime scenes‚ investigators often find unknown materials that need to be identified. If an unknown material is a mixture‚ an investigator may want to know one or two things about it: What are the ingredients of the mixture? Is the mixture found at the scene the same as a known mixture? A mixture is a collection

    Formation of an Alkene by Alcohol Dehydration Lab Report Balanced Chemical Equation for the Main Reaction Mechanism The acid-catalyzed dehydration of secondary and tertiary alcohols involves non-isolable carbocation intermediaries. In the first step of the of the reaction mechanism below‚ a phosphoric acid catalyst adds a proton to the oxygen atom of the alcohol to form an oxonium ion. The OH is converted to a better leaving group as the positive charge on the oxygen weakens the carbon-oxygen

    ALCOHOLS Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. For the purposes of UK A level‚ we will only look at compounds containing one -OH group. For example: Primary alcohols In a primary (1°) alcohol‚ the carbon which carries the -OH group is only attached to one alkyl group Some examples of primary alcohols include: Secondary alcohols In a secondary (2°) alcohol‚ the carbon with the -OH group attached is joined directly to

    Solubility and Stoichiometry I. Introduction The first purpose of this experiment is to apply solubility rules to choose two of eight given reactants to do a precipitation reaction. The second purpose is to use stoichiometry to calculate how much of a reactant will be used in a precipitation reaction‚ assuming that the amount of product is given‚ and to figure out the actual yield vs. the theoretical yield and to calculate the percent yield. The other purpose of this experiment is to practice the
