A little confused on the difference between Resonance and Isomer structures. Can you explain these to me with examples? I am in Organic Chem.
Carbonyl fluoride, , is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride
The 11B nucleus has a spin I of 3/2 and a nuclear g factor of 1.7920. At what field would resonance be observed at 60 MHz?
A sample of helium gas, He, at 22 degrees C and 101.3 kPa occupies a volume of 2.54L. At a constant pressure, what volume will it occupy at a liquid nitrogen tempature of -197 degrees C?
DNA polymerase (DNA pol) requires divalent magnesium for activity. Alcohol dehydrogenase (ADH) requires nicotinamide adenine dinucleotide
An unknown monoprotic weak acid, HA, has a molar mass of 55.0. A solution contains 2.50 g of HA dissolved 800. mL of solution. The solution has a pH of 2.000. What is the value of Ka for HA
Give the structure for an isomer of compound A that has a melting point that is appreciably different from that of A yet NMR spectra that are almost identical to those of A. Include wedge/dash bonds.
How many moles of PCl_5 can be produced from 21.0 g of P_4 and excess Cl_2?
Assume that the electrode follows the Nernst equation, the temperature is at 25°C, and that the activity coefficient of X is 1.
The reaction A=B+ C is second order in A. when [A}0=0.100M, the reaction is 20% complete in 35 minutes. Calculate the value of the rate constant in ( L/min.mol)
A robust first grader goes for swimming lessons three times a week, and he enjoys it thoroughly. During the first week of December, he develops an upper respiratory infection, starts coughing continuously, and has a high fever of 39°C.
A solution of ethanol (C2H5OH) in water is prepared by dissolving 72.0 mL of ethanol (density = 0.79 g/cm3) in enough water to make 300.0 mL of solution. What is the molarity of the ethanol in this solution?
When 50.0 mL of concentrated sulfuric acid is added to 1.15 g of sodium chloride, what volume (in mL) of hydrogen chloride gas is obtained at 1.00 atm pressure and 25oC?
