Why does a protic solvent favor E1 over E2? I know with Sn2 a protic solvent would surround the Nu: and hinder it from attacking, but in E2 there is not a nucleophilic attack.
A weak acid with the general formula of HA will react with a base, such as NaOH. Write the neutralization equation which describes the reaction.
List the basic solutions in order of increasing basicity. NH2OH, HNO2, C2H5NH2, NaNO2, and Ca(OH)2
The steel bomb of bomb calorimeter, which has a volume of 75 mL, is chaged with oxyen to a pressure of 145 atm at 22 C. Calculate the moles of oxygen in the bomb. Calculate the grams of oxygen in the bomb.
In which of the following carbohydrates are two different types of glycosidic bonds present
Carboxylic acids can be made by the hydrolysis of nitriles, which in turn can be made from an alkyl halide. Draw the structures of a starting alkyl bromide and the intermediate nitrile that would be used in the synthesis of phenylacetic acid
A solution is prepared by mixing 66.7 g H2O with 33.3 g HOCH2CH2OH (ethylene glycol). What is the concentration of ethylene glycol in units of molality? The molar masses of water and ethylene glycol are 18.02 g/mol and 62.07 g/mol, respectively
what would be the concentration in the pond (and outlet stream) after 2 days? Inlet and outlet flows are both 280 m3 per day.
At a temperature of 60 ºC, about 0.8 g CO2 can be dissolved in 100 g water. what would be the mass of CO2 which can be dissolved in 100 g water at 10 ºC?
A mixture of carbon and sulfur has a mass of 9.0 g. Complete combustion with excess O2gives 22.7 g of a mixture of CO2 and SO2
A compound has 2 ionizable groups, with pKas of 6.2 and 9.5. A 1.0 M solution of this compound (100 mL total volume) is found to have a pH of 6.8. A biochemist adds 60 mL of 1.0 M HCl to this solution. The solution pH is now:
