Show the mechanisms to form these products
Homework Answers
1.
This is Grignard reaction, in which first Grignard reagent will
form and which will attack on Acetaldehyde to get alcohol as a
product.
2. This cyclistion reaction in which aldehyde will get protonated and alcohol will attack on carbonyl carbon of aldehyde to get ether as a product.
3. This is acid amine coupling, in which first acid will get converted to acid chloride then amine will attack on it to get amide.
