how to determine the percentage difference between the experimental and the predicted value for the rate in 0.02M/sec, how could we predict rates at other concentration? if you have what you consider a large % difference how would you run the experiment to make it better
ow many stereo-isomers would there be if a molecule had four chiral centres, Rank the different carbocations in order of their stability.
