The image shows the chemical structure for ethyne (acetylene), HC. Here are some common reactions for ethyne: Step 1: Addition of Bromine (Br_2) Ethyne undergoes addition reactions with halogens like bromine. It can add two molecules of bromine across the triple bond. HC(g) + 2Br_2(aq) Br_2CH-CHBr_2(l) Ethyne + Bromine 1,1,2,2-Tetrabromoethane Step 2: Hydrogenation (Addition of H_2) Ethyne can be fully hydrogenated to an alkane by adding two molecules of hydrogen in the presence of a metal catalyst (e.g., Nickel, Platinum, or Palladium). HC(g) + 2H_2(g) Ni or Pt or Pd CH_3-CH_3(g) Ethyne + Hydrogen Ethane Step 3: Hydration (Addition of H_2O) Ethyne reacts with water in the presence of mercury(II) sulfate (HgSO_4) and sulfuric acid (H_2SO_4) to form an enol, which immediately tautomerizes to acetaldehyde. HC(g) + H_2O(l) HgSO_4, H_2SO_4 CH_3CHO(l) Ethyne + Water Acetaldehyde That's 2 down. 3 left today — send the next one.
