Final answer:
Different agents can be used for selective or partial oxidation of carbohydrates, such as mild oxidizing agents like bromine or strong oxidizing agents like nitric acid.
Step-by-step explanation:
For selective or partial oxidation of carbohydrates, different agents can be used depending on the desired outcome. Mild oxidizing agents such as bromine can be used to convert the aldehydic group of carbohydrates into an acid group, while strong oxidizing agents like nitric acid can oxidize the primary alcohol of carbohydrates forming saccharic acids.
