Two gas cylinders contain ethylene (ethene) and acetylene respectively. One test which can be used to distinguish between them is by?

Silver nitrate solution is used 2 distinguish alkene 4rm alkyne yl bromine water is used 2 distinguish alkane 4rm alkene

i think dat ammonical cupper also do d same as silver nitrate

yes... bcos ethene do not react to AGNO3 while ethyne will do giving out a whitish yellowish precipitate and silvercarbide

passing 2ru br.water is used to differentiate saturated hc frm unsaturated hc since alkene and alkyne ar both unsaturated hc so d most test to differentiate dem is by AgNO3 i.esilverniterate

yeah
silver nitrate or tollen reageant or Agno3.

acetylene(ethyne) forms reddish brown ppt with ammonical solution of copper(i)chloride and forms whitish yellow ppt with ammoniacal solution of silver nitrate(AGNO3). But ethylene (ethene) does not undergo any of thesr reactions

Now according to the reactions,

2Fe²⁺ on the left hand side and 2Fe³⁺ on the right.

2Fe²⁺ ------------> 2Fe³⁺ + 2e⁻
loss of electron is oxidation.



while for 2Cl⁻ on the right and Cl₂ on the left. The reaction is thus,

Cl₂ + 2e⁻ -----------> 2Cl⁻
gain of electron is reduction

so the idea is;
loss of electron / oxidation / reducing agent


gain of electron / reduction / oxidizing agent

so with these, Cl₂ is obviously correct. ✔️✔️
