For the experiment I started with 3.79g of benzyltriphenyl phosphonium chloride and ended up with 1.624g. What is my theoretical and percent yield? Molecular weight of benzyltriphenyl phosphonium chloride: 388.875 g/mol. Density: 1.18 g/cm^3 No chemical reaction given. Please tell me exactly what you need to figure out the answer. Experiment was "Preparation of (Z)- and (E)-stilbenes by a Wittig Reaction"
the top half of the image depicts the synthesis of
2-[(3,4-dimethoxyphenyl)methylene]-2,3-dihydro-1H-inden-1-one from
1-indanone and 3,4-dimethoxybenzaldehyde. The bottom half of the
image attached shows the table of chemicals used in the reaction.
How would I calculate theoretical yield and furthermore, the
percent yield? This experiment had a lot of chemicals used and I
don't know where to start.
