Lemieux reagent consist of an aqueous solution of sodium periodate `(NaIO_(4))` and a trace of `KMnO_(4)` It is used for locating the position of double bond in an alkene. During the reaction, the alkene is first oxidised to cis-diol which upon cleavage with sodium peroxide gives aldehydes and ketones (similar to ozonolysis). Hot solution of acidic or alkaline `KMnO_(4)` can also be used for locating double bond by observing the products which are ketones or carboxylic acids. Position of triple bond can be identified by similar process.
An alkene on treatment with `NaIO_(4) , KMnO_(4) "and" Na_(2)O_(2)` gives acetone and acetaldehyde. The alkene is :

Position of triple bond can be identified by similar process. An aromatic hydrocarbon (Y) on treatment with KMnO_(4) with H^(+)//Delta square gives benzoic acid as one of the products. The hydrocarbon (Y) is :
