intermolecular attraction and evaporation lab , chemistry2

Explain the variations in evaporation rate based on difference in intermolecular forces. What is controlling the change in evaporation rate for each class of substance? 2. What evidence do you see that hydrogen bonding is stronger than other intermolecular forces? What evidence do you see that intermolecular forces within alkanes are different than those in ketones? 3. Using your understanding of intermolecular forces, explain the difference seen in the evaporation rates for 1-propanol vs 2-propanol. (If your experimental results do not show a difference, please discuss whether you would have predicted there to be a difference, and why.) 4. Using your understanding of intermolecular forces, explain the difference seen in the evaporation rates of pentane vs iso-pentane. (If your experimental results do not show a difference, please discuss whether you would have predicted there to be a difference, and why.) 5. Based off of your observations for 1-propanol and 2-propanol, which do you expect to have a higher rate of evaporation: 1-butanol or 2-butanol? Using your data for the maximum temperature changes of 1-propanol, 2-propanol, and 1-butanol, predict the expected maximum temperature change of 2butanol
