Write a mechanism for the reaction of an alkyl halide with alcoholic silver nitrate which depicts the type of substitution which occurs. Explain how this mechanism accounts for the relative rate of reactivity of 1o, 2o and 3o halides in this reaction.
Present a reaction mechanism for the sodium iodide in acetone test which explains the relative rate of reactivity of 1o , 2o and 3o halides. Propose an explanation for the slow reaction of chlorides relative to bromides in this reaction.
