Nucelophilic Addition Elimination (Acid Anhydride and Amine)
Переглядів 331Рік тому
AQA A-Level Chemistry - Nucleophilic Addition-Elimination mechanism to form amides. The same mechanism works with water or alcohol acting as the nucleophile to form carboxylic acids and esters. I suggest watching the Nucleophilic Addition Elimination (Acyl Chloride and Ammonia) video first (ua-cam.com/video/KQGh-ovty-M/v-deo.html)
