a) oxidation number of carbon increases -4 to -2 hence oxidation
b)Chromic oxidation converts toluene to benzoic acid
c) LiAlH4 reduction convert iodopropane to propane
d) addition of HBr.The H+ added to cyclohexene reduce one double bond carbon and addition of Br- to carbocation oxidise another carbon Hence no overall change in reaction
e) Reduction of Aromatic compound by Na in liquid NH3 is called Birch reduction
