Comparison of Three Isomers of Butanol - 1448 Words

Comparison of Three Isomers of Butanol SCH 4UI Abstract The Hydroxyl group on alcohols relates to their reactivity. This concept was explored by answering the question â€Å"Does each alcohol undergo halogenation and controlled oxidation?† . Using three isomers of butanol; the primary 1-butanol, the secondary 2-butanol and the tertiary 2-methyl-2-propanol, also referred to as T-butanol, two experiments were performed to test the capabilities of the alcohols. When mixed with hydrochloric acid in a glass test tube, the primary alcohol and secondary alcohols were expected to halogenate, however the secondary and tertiary ended up doing so. This may have been because of the orientation of the Hydroxyl group when butanol is in a different†¦show more content†¦Three test tubes were placed in a test tube rack.. 2. Using a clean eye dropper, 2 drops of 1-butanol were placed in the first tube, 2 drops of 2-butanol were placed in the second tube, and 2 drops of T-butanol were placed in the third tube. 3. Under a fume hood, drops of concentrated HCl(aq) were added to each test tube. 4. Each mixture was shaken gently and subsequently returned to the test tube rack. 5. The tubes were observed for approximately a minute, noting any evidence of cloudiness. 6. The mixtures were then correctly disposed of, and steps 1. and 2. were repeated. 7. To each fresh tube of alcohol, 2 mL of 0.01 mol/L KMnO4 was added, and step 4. was repeated. 8. The Tubes were observed for a final 5 minutes, noting any color changes in the solutions.

The location of this hydroxyl functional group will impact the molecular structure of the alcohol, making it either primary (1 ° ), secondary (2 ° ), or tertiary (3 ° ). If the OH is bonded to only one other carbon, it is a primary alcohol (eg. 1-butanol); if bonded to two other carbons, it is a secondary alcohol (eg. 2-butanol); ifRead MoreEfficiency Of Alcohols Based On Chain Length And Branch Chains1674 Words   |  7 Pagesdetermine which alcohol is most energy efficient, including comparing the energy difference between straight-chain alcohols and their isomers. Due to the fact that the structure of the branch-chained isomer makes the molecule more compact and decreases its surface area, this reduces the intermolecular forces and therefore boiling point. It is hypothesised that isomers will require less energy to break the compound than straight-chain molecules and that as the number of carbon atoms increase in a straight-chainRead MoreChemistry And Biochemical Engineering : The Fields Of Synthetic Biology And Chemical Engineering1270 Words   |  6 Pagescom plex products that are difficult to synthesize chemically. In fact, the workhorses of biology- enzymes- enable high specificity in biochemical transformations (for example, to isomerize small molecules, or to act on a specific isomer preferentially over a different isomer) that has not yet been possible via chemistry alone. Thus, applying the synthetic biology toolbox to harness the amazing diversity and capability of protein-based catalysts for accelerating metabolic engineering efforts is of greatRead MoreMelting Point and Boiling Point of Organic Compounds3218 Words   |  13 Pagesmelting point apparatus was used for the first part of the experiment, while the micro method for boiling point determination was performed for the second. Both the melting and boiling point of compounds are affected by intermolecular forces. The three kinds of intermolecular forces that can operate on covalent molecules listed by increasing strength are van der Waals forces, dipole-dipole attraction s, and hydrogen bonds. Also, purity and isomerism also affect melting point and branching for boiling
