Task 1. Draw a line diagram of an alcohol that satisfies the following criteria:
Molecular formula: C8H18O2
Has exactly two hydroxyl groups.
One hydroxyl group is a 1º alcohol
One hydroxyl group is a 3º alcohol
Name this compound.
The boiling point of ethane is -89ºC.
The boiling point of n-octane is 126ºC.
The b.p. of “ethylene glycol” (pictured below) is 197ºC.
Provide a rough estimation of the boiling point of your alcohol and explain why in 30 words.
A sample of pure PCl5 was introduced into an evacuated vessel at 473 K. After equilibrium was reached, the concentration of PCl5 was found to be 0.5 x 10-1 mol L-1. If Kc is 8.3 x 10-3 what are the concentrations of PCl3 and Cl2 at equilibrium?
A 0.299 g sample of a gas was held in a 0.220 L container at 25.0°C and its pressure
was determined to be 0.757 atm. What is the molar mass of the gas?
