Steam Distillation of Lemongrass Oil I. Introduction When a mixture of cyclohexane and toluene is distilled‚ the boiling point of these two miscible liquids is between the boiling points of each of the pure components. By contrast‚ if a mixture of benzene and water (Immiscible liquids) is distilled‚ the boiling point of the mixture will be found below the boiling point of each pure component. Since the two liquids are essentially insoluble in each other‚ the benzene molecules in a droplet of

When butane’s dihedral angle was at 0⁰ and 360‚ the conformations are at an Emax. This means that the two methyl groups are eclipsed. At 60⁰ and 300⁰‚ which have gauche conformations‚ the methyl groups are more shifted and the potential energy difference is 18.2 kj/mol. At 120⁰ and 240⁰‚ eclipsed again‚ the energy rises to -4.6788 kj/mol‚ from its previous -17.721 kj/mol‚ the hydrogens can be found lying on the same plane‚ increasing the energy. Yet‚ the energy is not as high as it is at 0⁰ and 360⁰

Reactions: Procedure: 1. Measure 120 mg of 1‚4-dimethoxybenzene‚ 0.4 mL acetic acid‚ and 0.2 mL t-butyl alcohol 2. In a 10X100 mm reaction tube‚ dissolve the120 mg of 1‚4-dimethoxybenzene in the 0.4 mL of acetic acid. 3. Gently warm the solution within the reaction tube‚ it may be necessary to agitate the solution with a glass stirring rod and add the 0.2 mL of t-butyl alcohol 4. Cool the solution in an ice bath‚ once the solution is sufficiently cooled‚ place the reaction tube

alcohols are oxidized to ketones. Tertiary alcohols are not oxidized at all by the reagent. Hence‚ this reaction can be used to distinguish tertiary alcohols form primary and secondary alcohols. Procedures: 1. Place ethanol‚ isopropyl alcohol and tert-butyl alcohol in three different test tubes. Label them accordingly. 2. Add potassium dichromate solution to each of the test tube. Mix thoroughly. 3. Cautiously add concentrated sulfuric acid and mix. 4. Observe the change in color of

Experiment No. 1: MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting
