WebThen a water molecule rapidly, and reversibly, removes the proton in another acid–base reaction to leave the iodoketone. For the slow step (3), the rate depends on the isomerisation of protonated ketone/carbocation, which in turn will depend on the concentration of the ketone AND the acid providing the H 3 O + ion. Note: WebA reaction between the ketone and bromine water is an electrophilic alpha substitution reaction, adjacent to the carbonyl group and gives the colourless solution of … WebAlkenes react spontaneously with bromine water due to their unsaturated nature. The reaction between an alkene and bromine involves the breaking open of the alkene’s double bond and the inclusion of bromine in its structure (an addition reaction). This results in the production of an alkane with two bromine functional groups. business intelligence report template
