Preparation of and alpha, beta-unsaturated ketone via Michael and Aldol Condensation: 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexanone.
Draw a mechanism for each of the three steps in the preparation of 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone. You may assume that NaOH functions as a base and ethanol serves as a proton source
0.74 L of a 0.41 M solution is diluted to a final volume of 3200 mL. What is the resultant molarity?
Consider the molecules ClF3O and BrF3O. (a) Would expect the lone pair on the central halogen to be axial or equatorial in these molecules? Explain
Nitrogen and oxygen do not react appreciably at room temperature, as illustrated by our atmosphere. But at high temperatures, the reaction below can proceed to a measurable extent.
Assuming that the volume of a solid or liquid was independent of the external pressure, we deduced that there was no change in the Gibbs free energy of a solid or liquid when the pressure is changed.
Consider the reaction that occurs when a solution containing hydrochloric acid (HCl) is added to a solution containing the weak base methylamine (CH3NH2).
A small immersion heater is used to heat 475 mL of water from 75 degrees Fahrenheit to 195 degrees fahrenheit in 5.00 minutes.
How many grams of methane gas (CH4) are in a 15.8 liter sample at 1.2 atmospheres and 27°C? Show all work used to solve this problem.
1.90-g sample of a large biomolecule was dissolved in 23.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85°C. Calculate the molar mass of the biomolecule.
A 100.0 mL sample of 0.18 M HClO4 is titrated with 0.27 M LiOH. Determine the pH of the solution before the addition of any LiOH.
Compound A (C10H16O3) is insoluble in H2O, but soluble in bicarbonate solution. It yields a 2,4-dinitrophenylhydrazone derivative. Catalytic hydrogenation of Compound A
What is the gauge pressure of the gas in this mercury manometer if h = 53 mm and the atmospheric pressure is 781 mmHg? What is the absolute pressure of the gas?
Calculate the molarity of a solution made by dissolving 12.1 grams of Na2CrO4 in enough water to form exactly 520 mL
