If Hg and 1.50g O2 are obtained from heating 56.0g HgO, what is the masspercent yield of O2 ? Hint work out the stoichiometry of the reaction first.
What type of forces must be overcome when solid I2 is dissolved in dissolves in methanol, CH3OH? What type of forces must be disrupted between methanol molecules when I2 is dissolved?
This was allowed to react under reflux for an hour and then the products seperated. I wrote out a mechanism before lab and ended up predicting 4-chlorobenzoic acid and 4-chlorophenol as my final products.
Write an equation for the formation of an acetal from reaction of excess methanol with benzaldehyde in the presence of an acid catalyst.
Draw a flow sheet to show how you would separate the components of a mixture containing an acid substance, toluic acid; a basic substance, p-bromo-aniling and a neutral substance, anthracene.
