is finally tested to determine whether or not it has been dehydrated. The three tests used were infrared spectroscopy‚ Bromine chemical test and Bayer’s chemical test. The infrared spectroscopy showed a large narrow peak at 3062.12(cm-1) and 3020.71(cm-1) which indicates that there is a double bond present. To assure the results were correct the chemical tests were done. The Bromine test was found to be positive for cyclohexene. The OH group was removed from the cyclohexanol and replaced with a double

Purpose: The purpose of this experiment is to determine the nucleophilic strength of chloride and bromide ions as it reacts with 1-butanol (n-butyl) and 2-methyl-2-propanol (t-butyl alcohol) under SN1 and SN2 conditions. Method: 40 g of ice and approximately 30 ml of sulfuric acid is cautiously added to a 100 mL beaker respectively. Weigh 7.6 g of ammonium chloride and 14.0 g of ammonium bromide and place it in another beaker‚ crushing the lumps until a powdery mixture remains. The powdery mixture

Experiment 14: Preparation of 1-Bromobutane Goal: To prepare 1-Bromobutane by the SN2 reaction from 1-Butanol with Sodium Bromide and Sulfuric Acid. Mechanism: Procedure: 1. Place 27g of NaBr‚ 20mL of n-butyl alcohol‚ and 30mL of water into a 250mL round bottom flask. 2. Put the mixture in an ice-water batch and cool briefly‚ then slowly add 23 mL of conc H2SO4 while stirring with a magnetic stirrer. 3. Place a water-cooled condenser and heat the flask until the mixture boils while

Procedure: The experimental laboratory procedures were divided into two categories. First the formation of phenylmagnesium bromide‚ and second the reaction of the phenylmagnesium bromide with the carbonyl compound. However‚ before any of this could be done‚ the refluxing apparatus for the Grignard reaction was to be flame dried until no moisture remained inside because any water would cause the reagent to decompose and an alkane to form. The reaction would subsequently fail. Drierite was placed

Upon addition of bromine‚ the brown color of bromine quickly disappears as the bromine adds to the double bond in the products. Addition of bromine to the fractional distillate caused the bromine to discolor. The addition of bromine to 2-methyl-cyclohexanol remains brown because there is an absence of double bound (saturation). Addition of potassium permanganate caused the
