QUESTION 2 2.1 (8) 2.2 Ethanol has a boiling point of 78.5°C while dimethyl ether has a boiling point of -24.9°C. Account for this difference in boiling point since they both have the same molecular weight. Use diagrams in your explanation. Compare the acid strengths of CHFCH2CO2H and CH3CHFCO2H? Draw labelled Newman projections for the least and the most stable conformation that results from rotation of the C2-C3 bond of butane. (4) 2.3 (5) 2.4 (5) 2.5 Draw labelled Newman projections of the chair and boat conformations of cyclohexane. Which of these conformations is the more stable? Draw labelled sawhorse formulae of the two chair conformations of methyl cyclohexane showing the two possible positions of the methyl group. Which of these conformations is the more stable? (5) [27]
