The Correct Option is
Solution and Explanation
Concept: Reaction mechanisms
---
Step 1: Understand nucleophilic addition
Occurs when:
• Nucleophile attacks carbonyl carbon
• Forms addition product ---
Step 2: Analyze reactions
• Kolbe → substitution
• Williamson → substitution
• Reimer-Tiemann → substitution
• Electrolysis → redox
• Aldol → nucleophilic addition ---
Step 3: Aldol mechanism
• Enolate ion acts as nucleophile
• Attacks another carbonyl compound --- Final Answer: \[ \boxed{\text{Aldol formation}} \]
