1. Formation of Halohydrins; 2. Lab calculations1. Give mechanisms to account for the stereochemistry of the products observed from the addition of bromine to cis- and trans-2-butene. Why are two products formed from the cis isomer but only one from the trans?
2. Calculate how many milliliters of carbon dioxide would be produced theoretically from 20g of sucrose at 25 degrees Celsius and 1 atomosphere pressure.
Calculate [CO32- ] in a 0.025 M solution of CO2 in water (H2CO3). If all the CO32- in this solution comes from the reaction shown below, what percentage of the H+ ions in the solution is a result of the dissociation of HCO3‾?
