1. 1,3-diester is less acidic than a 1,3-ketoester, which is less acidic than an 1,3-diketone due to increased electron donation by the -OR group of the ester.
2. Claisen reactions use a stoichiometric amount of base and do not polymerize, unlike aldol reactions that use a catalytic amount of base and can polymerize.
3. Beta-hydroxy ketones can be formed by thiazolium catalysis with aldehydes.
4. Aliphatic heterocycles typically act like normal ethers, amines, and thioethers unless there is a large amount of ring strain.
A sample of gas is collected over water at a temperature of 35.0?C when the barometric pressure reading is 625 torr. What is the partial pressure of the dry gas, given PH2O = 42.2 torr?
Once the pKw's at the three temperatures are determined, the Van't Hoff equation can be used to determine Delta H for the reaction, and from that Delta G, and Delta S can be calculated.
What minimum OH- concentration must be attained (for example adding NaOH) to decrease the Mg2+ concentration in a solution of Mg(NO3)2 to less than 1.1e-10 M
Consider 1.00 L of air in a patient's lungs at 37.0 C and 1.00 atm pressure. What volume would this air occupy if it were at 25.0°C under a pressure of 5.00* 10-2 atm (a typical pressure in a compressed air cylinder)?
Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas. A gas vessel is charged with a mixture of PCl3(g) and Cl2(g)
Octane has a density of 0.692 g/mL at 20 degrees celsius How many grams of oxygen are required to burn 1.10 gal of octance.
Solar furnaces are designed to focus sunlight (say, with a parabolic mirror ) onto a relatively small area. given that the surface temperature of the sun is about 600K.
Consider the chemical bonds found in the white solid, potassium hydrogen phosphate, K2HPO4. For each bond specified, choose the best description from the list of types below.
A power plant burns 10^4 kg hr-1 of coal containing 2.5% sulfur. The effluent is released from a single stack of height 70 m. The plume rise is normally about 30 m.
What is the molality of a solution in which 25 g of sodium chloride is dissolved in 2.0 kg of water
calculate the mass of ammonium nitrate that should be heated to obtain 100 mL of dinitrogen oxide, N2O, at 1.00 atm and 25 degrees celcius?
14 g of Si reacts with 16 g of O to produce SiO2, the only product, with no reactant left over. How much SiO2 would be produced from 34 g of Si and excess O?
