Enantiomer of cis-1-chloro-3-methylcyclopentane
Draw the enantiomer of cis-1-chloro-3-methylcyclopentane which is R at C-1.
1) What is the configuration of this molecule at C-3 (R and S)?
2) When cis-1-chloro-3-methylcyclopentane and trans-1-chloro-3-methylcyclopentane are treated with sodium iodide in aqueous acetone, their rates of substitution are strikingly different. Explain clearly why this is so.
A mixture of helium and neon gases is collected over water at 28.0 C and 745 mmHg. if the partial pressure of helium is 368 mmHg, what is the partial pressure of neon?
Your metropolitan area has been warned by the EPA to lower sulfur dioxide and nitrogen oxide emissions or it will lose substantial federal funding. One citizen's group calls for conservation as a means of drastically reducing electricity consumption.
At a certain temperature the rate of effusion of helium is twice the rate of effusion of a gaseous X.X is a binary combination of carbon and hydrgen.
Calculate the specific heat was? Would your computed specific heat be , too low, too high or not affected if you had not dried the metal before placing it into the Styrofoam cup. Explain your answer?
The activation energy for the following reaction is 60. kJ/mol. Sn2+ + 2Co3+ → Sn4+ + 2Co2+ By what factor (how many times) will the rate constant increase.
How much heat is evolved in converting 1.00 mol of steam at 130.0 C to ice at -50.0 C? The heat capacity of steam is 2.01 J/g*C and of ice is 2.09 J/g*C.
The standard free energy of activation of a reaction X is 89.4 kJ mol-1 at 298 K. Reaction Y is one million times faster than reaction X at the same temperature.
