The rates of addition of molecular bromine in acetic acid to a number of acetylenes have been found to follow the general equationIn the absence of bromide ion and at low bromine concentrations (< 2 × 10−4 M), only the k2 process is observable. These k2 values for a series of ring-substituted phenylacetylenes are correlated well with σ+ values and give a ρ value of −5.17 which is interpreted in terms
