Question

Chemical test to distinguish between but-1-ene and but-2-yne

Answer 1

But-1-yne + KMnO4 /H+ = Butane -2-3 di one

but-2-yne + KMnO4 /H+ = Butanal -1- one

Answer 2

Both have different functional group

One contains double bond while the other contains a triple bond..

One is oliffin another one is a paraffin..

Both possess different chemical properties..

These compounds are distinguished by ammonia cuprous chloride and ammonical silver nitrate..

If ammonical cuprous chloride gives red ppt , it is an alkyne and if ammonical silver nitrate gives white ppt , it is an alkyne...
