### Step-by-Step Text Solution for Ozonolysis **Step 1: Understanding Ozonolysis** Ozonolysis is a reaction where alkenes react with ozone (O₃) to form ozonides. These ozonides are then cleaved in the presence of a reducing agent (like zinc dust) and water to yield aldehydes and/or ketones. **Step 2: Reaction with Ozone** Consider an alkene, for example, propene (CH₃-CH=CH₂). When propene reacts with ozone, the double bond between the carbon atoms reacts with ozone to form an ozonide. The structure of the ozonide can be represented as follows: - Ozonide structure: CH₃-CH(O)-O-O-CH₂ ...

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.
