Comprehension The first demonstration of the stereochemistry of the S_(N^2) reaction was carried out in 1934 by Prof. E.D Hughes and his colleagues at the University of London. They allowed (R) -2- iodooctane to react with radioactive iodide ion (""^(**)I-) The rate of substitution (rate constant K_5 ) was determined by measuring the rate of incorporation of radioactivity into the alkyl halide. The rate of loss of optical acitivity from the alkyl halide (rate constant K_0 ) was also determined under the same conditions: What ratio K_0//K_s is predicted for each of the following stereochemical scenarios : For inversion reaction :
