प्रश्न
How does the branching of hydrocarbon chain of synthetic detergents affect their biodegradability?

Straight chain hydrocarbons in synthetic detergent leads to easy biodegradability because the branched-chain hydrocarbon tail is a source of pollution. Therefore, lesser the branching more is the biodegradability.
