Predict the products likely to be formed via the anti-addition of Br2/DCM to trans-cinnamic acid.
Draw Fischer projection formulas for the products likely to be obtained from the bromination of (Z)-2-hexene with Br2/DCM. Identify the chiral centers with asterisks and label each center as R or S.
How we synthesis picric acid why it required 1 hour for the reaction with HNO3, H2SO4 and show the mechanism of picric acid and uses of picric acid and what is the role of HNO3, H2SO4 in the formation of picric acid
Calculate the acidity constant of benzoic acid in water at 298K if Delta Gf for C6H5CO2-(aq) is -269.2 kj/mol and delta Gf for C6H5COOH(aq) is -293.1 kj/mol. (The Delta Gf has a degree symbol on it if that is needed.)
the rate constant for the hydrolysis of lactose to galactose and glucose at 25 degrees C is .21M^-1 s^-1. What is the final concentration of lactose after 3.4 hours if the initial concentration was 2.50M
