WebA phenol is an alcohol whose R group is a phenyl group. It is essential that the oxygen and the benzene ring be directly attached to each other. If there is a tetrahedral carbon between them, the compound is not a phenol but an alcohol. An important difference between phenols and alcohols lies in their acidities. WebThe extensive determination of fragmentation rates of aryl halide radical anions, due to Saveant and coworkers15a by electrochemical methods, indicates that they range from values of 10-2s-1 for nitro-substituted phenyl halides up to 1010 s-1 for />-cyanophenyl halides. These values are in agreement with measurements by pulse radiolysis 42. how to set main gmail account
