Which of the following is Hill's oxidant?

1. DCPIP
2. DCMU
3. Rubisco

Hi Student,
The correct answer is DCPIP. It is an electron acceptor.
Full forms are -
DCPIP –2,6-dichlorophenol-indophenol
DCMU –3-(3,4-dichlorophenyl)-1,1-dimethylurea)
CMU – It is not a chemical. In which context you want to ask?
