RankGuru · Accepted Answer

Aldehydes that **lack an $\alpha$-hydrogen** atom cannot form enolates and thus cannot undergo Aldol condensation. Instead, in the presence of concentrated alkali ($50\% NaOH$), they undergo the **Cannizzaro Reaction**.
- Nature: It is a **Self-Redox (Disproportionation)** reaction.
- Process: One molecule is reduced to an alcohol, while another molecule is oxidized to the salt of a carboxylic acid.
- Examples: **Formaldehyde ($HCHO$)** and **Benzaldehyde ($C_6H_5CHO$)**.
