Ethanol, methanol, 1-propanol, and 2-propanol are alcohols. Rationalize the evaporation data of these substances based the type(s) of IMFs present in each and the relative strengths of these.

Compare boiling points and solubilities in water for each pair of compounds. Explain your reasoning.a. Ammonia, NH 3 and methane, CH 4b. Pentanol, C 5 H 11 OH, and pentane, C 5 H 12

Henry's Law constant is 0.000600 mol/kg-bar and 0.00130 mol/kg.bar for N2 and O2 respectively at 25°C. What pressure of O2 is required to achieve the same solubility as 0.616 bar of N2 in units of atm? (1 bar = 0.9869 atm; 1 atm = 760 mmHg) O 1.3 atm 0.276 atm O 4.8 x 10-7 atm O 1.3 x 106 atm O 3.5 atm

1.) Are there any intermolecular forces (IMF’s) between water molecules and cyclohexane molecules? What kind(s)? Given this, what would the magnitude and sign of DHMIXING be for cyclohexane dissolving in water?   a) Are there any IMF’s between water molecules and other water molecules? What kind(s)? Given this, what would the magnitude and sign of DHSOLVENT be for cyclohexane dissolving in water?   c) Are there any IMF’s between cyclohexane molecules and other cyclohexane molecules? What kind(s)? Given this, what would the magnitude and sign of DHSOLUTE  be for cyclohexane dissolving in water?   d) Why do you think cyclohexane does not dissolve in water? Analyze this the way it was done in class, thinking about the three contributions to DHSOLUTION. What do you think the magnitude and sign of DHSOLUTION would be for dissolving cyclohexane in water?  (Explain.)  Would you expect these substances to dissolve in each other? Why?

Methylene chloride ("proper" IUPAC name= dichloromethane) is considered a nonpolar solvent. Which of the four types of compounds ( small proteins, large proteins, triglycerides, or lactose) should dissolve in methylene chloride? Explain.

A certain substance X condenses at a temperature of 113.6 °C. But if a 350. g sample of X is prepared with 25.1 g of urea (NH2)¸CÓ) dissolved in it, the 2 sample is found to have a condensation point of 116.4 °C instead. Calculate the molal boiling point elevation constant K, of X. Round your answer to 2 significant digits. - 1 II °C- mol · kg x10
