benzophenone molar mass
answer
182.21g
question
Which radical, the hydroxyl isopropyl radical or the benzhydrol radical, should be more stable?
answer
The benzhydrol radical should be more stable due to ring resonance
question
A student went to the stock room to get 2-propanol for his experiment. By mistake he grabbed the bottle labeled 2-methyl-2-propanol which he used in his experiment. When the student went to the roof to retrieve his sample he found that he had no crystals in his test tube. Why didn't the student's reaction work?
answer
2-methyl-2-propanol would not work because it lacks a hydrogen atom that can be extracted (to protonate the benzophenone)

question
calculating theoretical yield requires what
answer
balanced chemical equation, grams or mols of starting reactant, a molar ratio, and the product given in grams
question
how to calculate theoretical yield
answer
grams of starting reactant to mols of starting reactant, mols of starting reactant into molar ratio, mols of products to grams of product
question
percent yield
answer
(actual mass/theoretical mass)*100
