Question
Chapter 3, Problem 29EQ
Interpretation Introduction
Interpretation:
The products of the given reaction need to be identified.
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,
