1.	What is the role of metal or reagents written on arrows in the given chemical reactions ? (a) (b) `CH_(3)COOH+CH_(3)CH_(2)OHoverset("Conc.H_(2)SO_(4))toCH_(3)COOC_(2)H_(5)+H_(2)O` (c ) `CH_(3)CH_(2)OHunderset("Heat")overset("Alk."KMnO_(4))toCH_(3)COOH`
Answer» (a) Nickel (Ni) acts as a hydrogenation catalyst for the reaction. (b) Conc. `H_(2)SO_(4) ` removes a molecule of `H_(2)O` from the reaction mixture and acts as a dehydrating agent. (c) Alkaline `KMnO_(4)` acts as an oxidising agent and oxidises alcohol to ethanoic acid.
