What compounds are formed from the reaction of benzoyl chloride with the following reagents?
a. sodium acetate
b. water

검증된 단계별 안내

Step 1: Understand the reactivity of benzoyl chloride. Benzoyl chloride (C₆H₅COCl) is an acyl chloride, which is highly reactive due to the electron-withdrawing nature of the carbonyl group and the chlorine atom. It readily undergoes nucleophilic acyl substitution reactions.

Step 2: Analyze the reaction with sodium acetate (CH₃COONa). Sodium acetate acts as a nucleophile, where the acetate ion (CH₃COO⁻) attacks the carbonyl carbon of benzoyl chloride. This leads to the substitution of the chlorine atom with the acetate group, forming benzoyl acetate (C₆H₅COOCH₃) as the product.

Step 3: Write the reaction mechanism for sodium acetate. The acetate ion (CH₃COO⁻) attacks the electrophilic carbonyl carbon of benzoyl chloride, forming a tetrahedral intermediate. The intermediate collapses, expelling the chloride ion (Cl⁻) and forming benzoyl acetate.

Step 4: Analyze the reaction with water (H₂O). Water acts as a nucleophile, where the oxygen atom in water attacks the carbonyl carbon of benzoyl chloride. This results in the substitution of the chlorine atom with a hydroxyl group, forming benzoic acid (C₆H₅COOH).

Step 5: Write the reaction mechanism for water. The oxygen atom in water attacks the electrophilic carbonyl carbon of benzoyl chloride, forming a tetrahedral intermediate. The intermediate collapses, expelling the chloride ion (Cl⁻) and forming benzoic acid as the final product.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Acyl Chlorides

Acyl chlorides, such as benzoyl chloride, are reactive compounds containing a carbonyl group (C=O) bonded to a chlorine atom. They are known for their ability to undergo nucleophilic acyl substitution reactions, where the chlorine atom is replaced by a nucleophile. Understanding the reactivity of acyl chlorides is crucial for predicting the products formed when they react with various nucleophiles.

Nucleophilic Acyl Substitution

Nucleophilic acyl substitution is a fundamental reaction in organic chemistry where a nucleophile attacks the electrophilic carbon of an acyl compound, leading to the replacement of a leaving group (like Cl in acyl chlorides). This reaction is key to understanding how different reagents, such as sodium acetate and water, interact with benzoyl chloride to form distinct products based on the nature of the nucleophile.

Carboxylic Acid Derivatives

Carboxylic acid derivatives, including esters and acids, are formed from the reaction of acyl chlorides with various nucleophiles. In the case of sodium acetate, an ester is formed, while water leads to the formation of a carboxylic acid. Recognizing the types of derivatives produced from these reactions is essential for predicting the outcome of the reactions involving benzoyl chloride.
