I have the honour to state that I have faced some problem with those question below: 1.How to seperate each elements when they are exist in a one container:ethene,ethyne,ethane? 2.To produce Alkylbromide we need Alkanol,HBr and H 2 SO 4 but H 2 SO 4 is not necessary to produce Alkyliodide-Why? 3.Diamminecopperchloride [Cu(NH 3 ) 2 ]Cl reaction with Alkyl-1-yne but why it doesn’t reaction with Alkyl-2-yne or Alkyl-3-yne ? It will be grateful if anyone answer those question..please,please.

@ emon if u have a mixture of ethyne , ethane , and ethene . then u can separate it with the help of tollens reagent . on passing them,ethyne will give white precipitate . of silver acetylide .while rest of the gases will not show any reaction . ethyne can be regenarated by treating the white precipitate of disilver acetyldide . with dil . nitric acid . rest of the gases containing ethene and ethane passed through cold conc h2so4 , when ethene is absorbed as ethyne hydrogen sulphate , and ethane escape out which is collected . |the ethyl hydrogen sulphate will be collected in a separte container after heating . HOPE IT HELPS ALL THE BEST ..
