Comparison of Three Isomers of Butanol Introduction An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. 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° ). The purpose of this experiment is to observe and predict the reactions that take place between all three alcohols and an oxidizing agent‚ as well as to test our theories of how the

LAB: Comparison of Reactions for Three Isomers of Butanol /23 TI /21 C /6 A Name: /50 MARKS Background: The reactivity of alcohols can be accounted for by their molecular structure – particularly by the attachment of their hydroxyl functional group. The isomers of butanol are used as examples of 1°‚2° and 3° alcohols to examine this relationship. Each of the three isomers of butanol will be mixed with concentrated hydrochloric acid. The presence of an alkyl halide product is

Comparison of Three Isomers of Butanol Introduction: An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. 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); if bonded to

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 “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

Lab: Comparison of Three Isomers of Butanol Pre-lab: 1. Write the general reaction of an alcohol and HCl. 2. What would the solubility be of an alcohol in water. 3. What would the solubility be of an alkyl halide in water? 4. What is the purpose of KMnO4 in the reactions? Safety: Concentrated hydrochloric acid is corrosive and the vapour is very irritating to the respiratory system. Avoid contact with skin‚ eyes‚ clothing‚ and the lab bench. Wear eye protection and a lab apron.

results did support the concept that as the carbon number increased so would the energy level. When comparing the energy levels of other isomers to straight chain alcohols‚ the graph shows the first part of the trend line for the other isomers to have a higher energy‚ while the less steep trend gradient means this switches over between 3 and 4 carbon‚ indicating that isomers with a carbon atom number greater than that will have increasingly lower enthalpy levels. This variance in results when performed

The Increasing Enthalpy of Combustion Rates for Pentanol Isomers EEI Report Draft - JEREMY SAJU 11B Fuels are the main energy source of the modern world. The topic of this extended experimental investigation is to explore combustion rates of alcohols‚ specifically pentanol and it’s relationship with varying structural isomers. A fuel is defined as a material that stores potential energy that‚ when released‚ can be used as heat energy (Chemguide‚ 2003). The balanced combustion equation for pentanol

use of tert-butanol was needed to perform phase changes. Tert-butanol is colorless oily with sharp odors‚ mixes with water‚ and has a freezing point of 78 degrees Farenheit (PubChem‚ 2016). This substance allows for proper testing due to its freezing point being at room temperature. Tert-butanol can easily show how the process of phase changes can happen without having to take the time to freeze a different substance. It is also necessary to note the molecular formula. Tert-butanol is C4H10O‚ which
