when optically active (R)-2-bromoctane ([alpha] = +39.6 degrees) was allowed to react with a mixture of water and ethanol, 2-octanol with [alpha] obs of + 1.0 degrees was obtained as the major product. From the chemical literature it is known that optically pure (R)-2-octanol has a specific rotation of -10.0 degrees. What is the optical purity, or enantiomeric excess, of the 2-octanol produced in this reaction? 10% S. What is the ratio of enantiomers of 2-octanol in the product mixture? 55% (S) and 45% (R). However, I am not sure how to draw the structure of the major enantiomer produced in this reaction. Indicate the configuration of the stereogenic center using wedged and hashed lines.

Use the van der Waals parameters for chlorine to calculate approximate values of (a) the Boyle temperature of chlorine and (b) the radius of a Cl2 molecule regarded as a sphere.
200 mL of 1.00M NaOH is reacted with 200 mL of 1.00 M HCl in a calorimeter. The calorimeter and the solutions were at an initial temperature of 19.5oC before mixing.
The flask was then shaken until the solution was uniform. A 60.0ml- sample of this glucose solution was diluted to 0.500 L . How many grams of glucose are in 100.ml of the final solution?
What would be the wavelength of a photon that would be able to break the Cl-Cl bond in Cl2. The bond energy in Cl2 is 243 kJ/mol.
Fischer projections, isomers, enantiomers and stereocenters, For 2,3-butanediol, there are 3 isomers; 2 are enantiomers, one is not.
How many moles of ammonium ions are released when 1.6 mol of ammonium phosphate, (NH4)3PO4, is dissolved in water?
Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. Carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment.
Assume an organic compound has a partition coefficient between water and diethyl ether equal to 8.95. If there are initially 7.89 grams of the compound dissolved in 100.0 mL of water, how many grams will remain in the aqueous layer after extractio..
