In lab, we reacted 4-phenylbutyric acid with methanesulfonic acid to generate α-tetralone. How would the calculations for the theoretical yield look? If I, for example, had 0.500g of 4-phenylbutyric acid, how would the equation look? I know it's an intramolecular reaction, but I'm confused on how to write out of the equation for the theoretical yield. Typically it is: (mass of reactant) x (1 mol / molecular weight of reactant) x ( molar ratio of product / 1 mol of...

Can someone please help? Thank you.
ATOM ECONOMY: The traditional way of evaluating the efficiency of an organic reaction is to determine the percent yield of the reaction. Most organic chemists would be quite pleased with a reaction with >90% isolated yield of the target molecule. On the other hand, a yield of 30% is typically considered to be a disappointment. As a review of the concept of theoretical yield and percent yield, let's consider the following Sy2 reaction CH3CH2CH2CH2OH...
