The products of the reaction of propyl magnesium iodide with ethylene oxide need to be represented. Concept Introduction: The formation of a carbon-carbon sigma bond occurs in the reaction of a Grignard reagent with ethylene oxide. The Grignard reagent is usually alkyl magnesium bromide and written as an ion pair consisting of the MgBr+ ion and the alkyl anion. Below is the structure of Grignard reagent. Here, alkyl anion acts as the nucleophile. This helps in the ring opening and a new sigma bond formation as shown below,
