Practice Problem: Grignard Reactions

The video tutorial covers Grignard reactions, focusing on their mechanisms and applications. It explains how Grignard reagents form new carbon-carbon bonds by attacking carbonyl carbons, and emphasizes the importance of numbering carbons to track changes in molecular structure. The tutorial also discusses reactions involving ester substrates and excess Grignard reagents, highlighting the potential for consecutive reactions. Key concepts include nucleophilic attack, carbonyl regeneration, and the role of excess reagents.

Discuss the common errors that can occur when drawing the products of Grignard reactions.

How can numbering the carbons help in visualizing the transformation in Grignard reactions?

What is the outcome of a Grignard reaction when excess Grignard reagent is present?
