WebBut-1-yne, phenylacetylene, but-2-yne, and diphenylacetylene undergo hydrosilylation in 70–90% yield using diplatinum complexes [ {Pt (SiR 3 ) (µ-H) [ (C 6 H 11) 3 P]} 2 ] [SiR 3 = Si (CH 2 Ph)Me 2, SiCl 3, or SiEtMe 2] as catalysts. Many of the reactions proceed exothermically after initial warming of the reactants. WebCorrect option is A) Structure of 1 -butyne is HC≡C−CH 2−CH 3 Structure of 2 -butyne is H 3C−C≡C−CH 3 Ammonical siluer nitrate reacts with. acidic hydrogen to form a white precipitate. Terminal alkynes have acidic hydrogen. CH 3−CH 2C≡CH NH 4OHAgNO 3CH 3−CH 2−C≡C −Ag ++NH 4NO 3+H 2O So l-butyne gives white ppt but not 2 butyne.
