Hemiacetals & Acetals: Formation & Hydrolysis | Alcohol Addition | Organic Chemistry 19.4a

Chad provides a comprehensive lesson on the nucleophilic addition of alcohols to aldehydes and ketones to produce hemiacetals and acetals and hemiketals and ketals. He covers both the base catalyzed mechanism and the acid catalyzed mechanism including all arrow-pushing. He makes a quick point of showing how glucose commonly forms a hemiacetal and then concludes the lesson showing how acetal formation is reversible with H3O+ and explains how to predict the products of hydrolysis of acetals and ketals.
