The initial increase in the rates of ``on water'' reactions on the addition of alcoholic cosolvents is contrary to the sharp decrease in rates observed for homogeneous aqueous reactions. The existing theoretical framework is presented in terms of a typical ``on water'' process to enable a discussion of the experimental observations with reference to changing composition of the reaction medium. On the basis of the interesting observations of reactivity and selectivity variations with composition of the reaction medium, a simple ``signature'' characteristic for ``on water'' reactions is proposed.</p>1 aTiwari, Shraeddha1 aKumar, Anil  uhttps://library.ncl.res.in/content/interfacial-reactivity-water-reactions-presence-alcoholic-cosolvents-0
