1.	Write the changes observed on addition of the reagents (a) and (b) to the hydrocarbons (i), (ii) and (iii).Reagents: (a) ammoniacal copper (1) chloride solution(b) alkaline potassium permanganate solutionHydrocarbons: (i) ethane (ii) ethene (iii) ethyne
Answer» Solution :(i)ETHANE: No reaction with reagents (a) and (b (ii) Ethene: DECOLOURISES reagent (b) but no reaction with reagent (a) (iii) ETHYNE: GIVES red precipitate with reagent (a), and decolourises reagent (b)
