| 1) ammoniacal cuprous chloride 2) ammoniacal silver nitrate....(i think nitrate only) these two are used in detecting the triple bond-ethyne 1) gives red ppt and 2) gives white ppt.... |

| though u may not know me i thought i shud tell u...i think u people may know this but ther is another reagent...Baeyer's reagent...it is cold dil. alkaline KMnO4(potassium permanganate) soln...it oxidises ethene to ethylene glycol(ie. CH2OH-CH2OH) n also oxidises ethyne to oxalic acid(COOH-COOH)...n has no effect on alkanes... |
