Answer» Solution :DETERGENTS have long hydrocarbonchains. If their hydrocarbon chain is highly branched. Then bacteria cannot degrade this easily. Such detergents are non-biodegradable. SLOW degradationof detergents leads to their accournlation. These non-biodegradable detergents persist in water even after treatement and cause foarming in rivers, ponds and their wate get polluted. In order to overcome this issue BRANCHING of the hydrocarbon chain is K controlled and keptto minimum. |
