CHM 1046 – Complete Question & Answer Bank (2025/2026) 1. How would you prepare cyclohexylformate or cyclohexylbutycate? - ANSWER Cyclohexylformate can be formed by treating carbon monoxide with an alcohol, such as methanol, with a catalyst present and it will form as an ester. Cyclohexylbutycate can be formed the same way using a different base, alcohol, and catalyst. 2. If your experimental yield of aspirin is greater than 100% how could this occur? If your expe...

CHM 1046 – Practice Questions with Step-by-Step Solutions | Florida Chemistry II (2025/2026) 1. Solvation - ANSWER When a solvent is surrounding a molecule/ion 2. Hydration - ANSWER When the solvent surrounding a molecule/ion is water (H2O). 3. How do you compare the strength of non-polar molecules? - ANSWER The molecules have to have the same molecular formula and polarity. If they have different MWs, the molecule with a higher MW feels LDF more than the o...

Which of the following processes would you expect the entropy of the system to decrease? I. evaporating a liquid II. decreasing the temperature of a gas III. melting a solidII only The boiling point of pure methanol (CH3OH) is 338K and the boiling point of pure ethanol (CH3CH2OH) is 351K why is the boiling point of ethanol higher than methanol? a. because ethanol forms more hydrogen bonding interactions per molecule than methanol. b. because ethanol has a larger electron cloud and ther...
