Answer:
When acetaldehyde is treated with aqueous sodium hydroxide solution, it undergoes aldol condensation (because of the presence of α−H atom) as:
CH
3
CHO+HCH
2
CHO
Dil.aqueous
NaOH
CH
3
CH(OH)CH
2
CHO(shows optical isomerism)
Since, the aldol formed contains one asymmetric carbon atom, it will show optical isomerism.
On heating, aldol loses water and gives an alkene.
CH
2
CH(OH)CH
2
CHO
Δ
CH
3
CH=CHCHO
(shows geometrical isomerism)
The obtained alkene shows geometrical isomerism.

The compound that can be obtained by polymerization of acetaldehyde amorphous polyacetaldehyde
- Polymerization is a chemical process in which a monomer is converted into a polymer by joining many units of monomers under different chemical conditions (ph, temperature, pressure) which varies depending on the type of monomer.
- Polymerization of acetal leads to the formation of amorphous polyacetaldehyde with the following formula:
