confusing part of the organicum. we need to know the main test that distinguish ethene from ethyne since both are unsaturated hydrocarbons and as a result of this, both can decoulorise bromine water (BrOH) and acidified potassium tetraoxomanganate (VII) (KMno4). so how can we distinguish between these?<br /><br />the answer lies in the fact that ethyne has the power to undergo certain reactions with the insoluble salts of the noble metals, especially those of copper and silver.<br /><br />ethyne reacts with ammoniacal copper(I)chlorider(CuCl) copper(I)ethanoate(CH3COOCu) or copper(I)Nitrate(CuNO3) and with silver equivalence which are silver(I)chloride(AgCl), silver(I)ethanoate(CH3COOAg) and silver(I) nitrate(AgNO3). while ethene has no effect on all these salts. <br /><br />hence, here lies the main reaction that distinguish ethene or ethylene from ethyne or acetylene.<div class="blogger-post-footer"><img width='1' height='1'
