Reaction and mechanism of acetal formation from ketone or aldeyhde and an alcohol or diol.
[ad_1]
Acetal Formation: Acetal formation is a reaction in which an aldehyde or ketone reacts with two equivalents of alcohol to form an acetal. This reaction is catalyzed by an acid, typically a strong acid like hydrochloric acid or sulfuric acid.
Step-by-Step Process:
- Protonation of carbonyl oxygen
- Nucleophilic attack of alcohol
- Removal of water molecule
Conclusion: Acetal formation is an important reaction in organic chemistry that allows for the conversion of aldehydes and ketones into more stable acetals. This reaction is commonly used in the synthesis of various compounds in organic chemistry.
FAQs
Q: What is the role of acid in acetal formation?
A: The acid acts as a catalyst in the reaction, helping to protonate the carbonyl oxygen and facilitate the formation of the acetal.
Q: Can any alcohol be used in acetal formation?
A: Generally, primary alcohols are preferred for acetal formation, but secondary and tertiary alcohols can also be used in some cases.

this many years later and still a wonderful video! tysm for this !
Seriously helped so much! Especially the way you laid out, P-A-D-P-E-A-D and then the reverse P-E-A-D-P-E-D, except i was confused cause its not exactly the opposite haha
great video! can't believe no one comments!
