Which of the following compounds can be prepared by using Grignard reagent?
Correct answer: D. All of these
- A. Alkanes
- B. Alcohols
- C. Carboxylic acids
- D. All of these
Explanation
Option D, "All of these," is correct. Grignard reagents can be used for the preparation of alkanes, alcohols, and carboxylic acids through different reactions.- Alcohols: Grignard reagents react with carbonyl compounds (aldehydes and ketones) to form alcohols. - Alkanes: Grignard reagents can react with alkyl halides, leading to the formation of longer alkane chains.- Carboxylic Acids: Grignard reagents can also react with carbon dioxide to form carboxylic acids.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
