List 3 functional groups that must be avoided during the formation of a Grignard reagent. For each of the functional groups listed in your above answer, write chemical equations that demonstrate why those particular functional groups should be avoided.
Homework Answers
Groups with Acidic hydrogens are Grignard reagent sensitive sicne Grignard reagent is a good source for nucleophilie (Carbanion) which can easily attack the Electrophile (H+) of compounds with acidic hydrogens to form concerned alkanes
Examples include carboxylic acid , alcohols and Terinal alkynes

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

1. Define the term "Nucleophile" and explain how a Grignard reagent acts as a nucleophile. Briefly explain using a chemical equation, why it is necessary to use dry apparatus and reagents during the synthesis of C6H5MgBr. phenylmagnesium bromide. 3. By referring to a textbook, write a mechanism for the reaction between phenylmagnesium bromide and the ketone butanone. In a reaction of phenylmagnesium bromide with butanone the Grignard reagent was prepared from 25 g of...
