somebody please tell what can be oxidised by the following oxidising agents and to what extent
a. OsO4
b. NaBH4
c. dil KMnO4
d. Conc. KMnO4/OH-
e. CrO3/H+
please tell what are the conditions in presence of which these oxidising agents work.?
please tell any other oxidising agents that you know ..
and there function too...i am a little bit confused in their wwork and the conditions in which they work !! :( :( :(
1OK !! I can help u on this
replying in half an hou or so..have patience
1actually....NaBH4...is not a oxidising agent...
and CrO3/H+ is known as jones reagent....
Jones Oxidation
The Jones Oxidation allows a relatively inexpensive conversion of secondary alcohols to ketones and of most primary alcohols to carboxylic acids. The oxidation of primary allylic and benzylic alcohols gives aldehydes.
and OsO4 is a more powerful oxidizing agent than the halogens. It oxidizes the halides (Cl-(aq), Br-(aq), I-(aq)) to their respective halogens.
rxn follows::
2 Cl- (aq) --→ Cl2
OsO4 + 2 OH- (aq)--→ [OsO4(OH)2]2- [deep red]
and...KMnO4--
Dilute solutions of KMnO4 convert alkenes into diols (glycols). This behaviour is also used as a qualitative test for the presence of double or triple bonds in a molecule, since the reaction decolourises the permanganate solution; thus it is sometimes referred to as Baeyer's reagent.
Potassium permanganate oxidizes aldehydes to carboxylic acids, such as the conversion of n-heptanal to heptanoic acid:
C6H13CHO + [O] → C6H13COOH
and there are many oxidising agents such as...

39@ shriya: its something which cannot be exactly told as even if we tell a lot of it , we would miss something.
so i guess u probably come up chapter wise then it would be easy rather than reagent wise.
as its better oto remember exceptions and uses chapter wise and helps aa lot
