Question

what happen when -diiute hcl is treated with acetaldehydediethyl acetal

Answer 1

One way of acetal formation is the nucleophilic addition of an alcohol to a ketone or analdehyde. Acetalisation is often used in organic synthesis to create a protecting group because it is a reversible reaction. Acetalisation is acid catalysed with elimination of water; acetalsdo not form under basic conditions.
