Introduction
In chemistry, organic reactions often involve transforming one compound into another using specific reagents and conditions. When a question asks how the following conversion can be carried out, it’s inviting you to propose a step-by-step chemical pathway from the starting material to the target compound. This guide walks through how to approach such conversions, with strategies and examples to build your understanding.
General Approach to Organic Conversions
Step 1: Identify Functional Groups
- Examine the starting and target compounds.
- Note changes in the functional groups (e.g., alcohol to ketone, alkene to alkane).
Step 2: Compare Structures
- Count carbon atoms—are atoms added or removed?
- Look for changes in bonding (e.g., saturation, ring formation, rearrangement).
Step 3: Recall Common Reactions
- Oxidation, reduction, substitution, elimination, addition, rearrangement
- Use well-known reagents associated with specific transformations
Step 4: Plan Reaction Sequence
- Break down complex conversions into smaller steps
- Propose reagents for each step that lead logically to the target compound
Step 5: Justify Each Step
- Clearly explain the chemical reasoning behind each transformation
- Mention reaction conditions (solvent, temperature, catalyst if needed)
Example Conversion
Conversion: Alcohol → Alkene
Step-by-Step:
- Dehydration of Alcohol:
- Reagent: Concentrated H₂SO₄, heat
- Reaction: R–CH₂–CH₂OH → R–CH=CH₂ + H₂O
- Mechanism: E1 or E2 elimination, depending on substrate

Tips for Answering Exam-Style Conversion Questions
- Use arrow-pushing diagrams for clarity
- Keep reaction steps minimal (efficient synthesis)
- Label all reagents and conditions clearly
- Indicate any stereochemical outcomes if relevant
FAQs
What if I don’t know the exact reagent?
Use a general name (e.g., oxidizing agent) if you can’t recall the specific one, but try to be precise where possible.
Can a single conversion require multiple steps?
Yes, complex conversions often need two or more steps.
Should I include mechanism?
Only if the question asks for it—but brief justification is always good.
Conclusion
To answer how the following conversion can be carried out, begin by identifying the changes in structure and functional groups. Use known reactions and reagents to create a clear, logical sequence of steps. With practice and solid understanding of organic chemistry principles, these conversions become easier to predict and explain.
