1.	What is the role of metal or reagents written on arrows in the given chemical reactions? (a) {:(CH_(3)),("\"),(""C),("/"),(CH_(3)):}=C{:(" CH"_(3)),("/"),("\"),(" CH"_(3)):}+H_(2) overset(Ni)toCH_(3)-underset(H)underset(\|)overset(CH_(3))overset(\|)C-underset(H)underset(\|)overset(CH_(3))overset(\|)C-CH_(3) (b) CH_(3)COOH+CH_(3)CH_(2)OH overset("Conc. "H_(2)SO_(4))to CH_(3)COOC_(2)H_(5)+H_(2)O (c ) CH_(3)CH_(2)OH underset("Heat")overset("Alk. "KMnO_(4))to CH_(3)COOH
Answer» SOLUTION :(a) Ni ACTS as a catalyst. (b) Concentrated `H_(2)SO_(4)` acts as a catalyst and a dehydrating agent. (c ) Alkaline `KMnO_(4)` acts as an oxidising agent.
