If ethyl benzoate is treated with phenyl magnesium bromide (1:1) ratio, a one to one mixture of ethyl benzoate and triphenylmethanol are obtained after work-up instead of just benzophenone which might be expected. Explain these results. Draw out a detailed mechanism for the reaction including proper geometry, important resonance contributers, intermediates.
