Question

In a Crossed Cannizzaro reaction strictly between Formaldehyde ($HCHO$) and Benzaldehyde ($PhCHO$) using concentrated $NaOH$, what are the primary organic products?

Answer: A

💡 Solution & Explanation

Formaldehyde lacks steric hindrance and is always attacked by $OH^-$ first. It exclusively undergoes oxidation to sodium formate, forcing the bulkier benzaldehyde to accept the hydride and be reduced to benzyl alcohol.
