In organic chemistry, what is the significance of a Grignard reagent, and what type of reaction does it typically undergo?
Understand the Problem
The question is asking for the significance of Grignard reagents in organic chemistry, specifically asking about its role in chemical reactions. Based on the multiple-choice options, we need to identify the correct description of its function.
Answer
Grignard reagents form carbon-carbon bonds via nucleophilic addition, creating alcohols from carbonyls and alkanes from acidic hydrogens.
Grignard reagents are crucial in organic chemistry for forming new carbon-carbon bonds. They typically undergo nucleophilic addition reactions, especially with carbonyl compounds like aldehydes and ketones, to produce alcohols. They also react with acidic hydrogens to produce alkanes.

More Information
Grignard reagents are named after French chemist Victor Grignard, who won the Nobel Prize in Chemistry in 1912 for their discovery.
Tips
A common mistake is forgetting that Grignard reagents are strong bases and will react with acidic protons (like those in water or alcohols) before reacting with the desired electrophile. Always ensure your reaction environment is free of protic solvents.
