1.	Question : Describe briefly what was demonstrated in the reaction named after its discoverer Robin Hill?
Answer» SOLUTION : R. Hill (1937) found that when isolated CHLOROPLASTS from ground up leaves of Stellaria media placed in cell extracts, produced oxygen from `H_2 O` in illuminated stage. He also noticed that cell extracts can be replaced by SALTS of IRON like ferric oxalate. The substances when added to illuminated isolated chloroplasts in the absence of `CO_2` acted as hydrogen acceptors i.e. oxidants. These substances are called Hill oxidants or Hill REAGENTS.
