How to find the ratio in a wittig reaction of (E) and (Z) isomers of stilbenes? Started with 5g of sodium hydroxide and 3.8g of benzyltriphenylphosphonium chloride. They want us to find this ratio both before and after isomerization with 75mg of iodine. Also obtained IR, CNMR and HNMR data. Also, how to calculate theorectical yield. The final prodect weight was 3.1124g
Explain, phenomena in terms of atomic structure and behavior. When you lightly bump into a car, why does it dent and not create a hole.
Calculating percent purity from a reaction, One of the reactions that occurs in a blast furnace, where iron ore is converted to cast iron is Fe2O3 + CO = Fe + CO2.
(heatcapacity of water : 4.184 j/g/k) if the final temperature of the system is 30c, what is the specific heat capacity of the alloy
Assuming that you could express and purify both components, describe TWO different experimental methodologies (including SALIENT details) that you would conduct to determine whether the two proteins interact in vivo in a mammalian cell line?
An unknown compound X, is thought to have a carboxyl group with a pka of 2.0 and another ionizable group with a pka between 5 and 8. When 75 ml of 0.1 M NaOH was added to 100 ml of a 0.1 m solution of X at pH 2.0, the pH increased to 6.72.
