A pair of enantiomers is named below. For each stereoisomers, draw the structure. Be sure to specify the stereochemistry via wedge-and-dash bonds.
(R)-5,5-dibromo-3-fluoro-2-methyl-3-hexanol
Detailed analysis of the 369 and 295 cm-1 bands show them to arise from totally symmetric modes. Show that the Raman spectrum is consistent with a trigonal-bipyrimidal geometry.
Sodium formate, HCOONa, is a weak base and undergoes hydrolysis in water. Determine the OH- concentration at equilibrium in a solution
How much heat is required to convert 5.0 g of ice at -10.0 ?C to liquid water at 15.0 ?C? (Assume heat capacities are independent of temperature.)
Compute the ΔH for this reaction and express your answer in kilojoules if the given . Bond Energies (kJ/mol) are N-Cl 201 , Cl-Cl 243 , N-H 389 ,H-Cl 431
Use the masses of carbon dioxide, rm CO_2, and water, rm H_2O, to determine the empirical formula of the alkane component.
Calculate the change of volume of the cube at a depth of 1.000 km (disregarding the effects of temperature). Take the mean density of sea water as 1.03 g/cm3.
A 9.775 g. gaseous mixture contains ethane (C2H6) and propane (C3H8). Complete combustion to form carbon dioxide and water requires 1.120 mol of oxygen. Calculate the mass percent of ethane in the original mixture.
Research the number of electrons that can fit into energy levels higher than the third level. Why does that explain why there is a space in the lower periods of the periodic table?
