Vedclass · Answer

(D) Biodegradability of surfactants depends on the structure of the hydrocarbon chain. Straight-chain alkylbenzene sulfonates are more easily degraded by microorganisms than branched-chain ones. Highly branched alkylbenzene sulfonates,such as the one shown in option $D$,are resistant to microbial attack because the branching hinders the enzymatic degradation process. Therefore,the highly branched structure makes it the least biodegradable.
