It also looks in … WebReactivity towards HCN is provided by Cu 2+ ions complexed by the diamines. Overall reactivity towards the two gases depends on the balance between free amine and Cu 2+ concentrations. The performance of these adsorbents is superior to that of carbon-based adsorbents in which alkylamine and copper( II ) salt are physisorbed on the carbon surface.
WebApr 7, 2024 · Addition of HCN is a nucleophilic addition reaction. Complete step by step answer: Here, HCN is added to carbonyl groups, such reactions are called nucleophilic addition reactions, so reactivity will also be judged on the basis of addition of nucleophiles. WebThe reactivity of a compound depends on the steric hindrance due to the groups present around the carbonyl group. Greater the steric hindrance, less will be the reactivity of the compound.
