A 0.20M aqueous solution of a solute that is non-volatile electrolyte wtih a molar mass of 100g/mol has an osmotic pressure of 12atm at 298K. The density of the solution is 1.20 g/cm3 what is the boiling point of this solution? Kb=0.52 C/m
Norborneol synthesis in this manner is stereoselective. So, there are two possible products one endo and one exo. Only one will form, but why aren't there actually four possible products since the alcohol can form on either carbon in the alkene?
