Organic Chemistry Lab Report Format

Format • • Title Objective Introduction Method Result Discussion Conclusion References

Objective • Remove student word

Introduction • State the objectives of the experiment • Include background theory, previous research, or formulas the reader needs to know • Do not copy from lab manual • One paragraph should be sufficient

Introduction Verb • The experiment is already finished. Use the past tense when talking about the experiment. “The objective of the experiment was…” • The report, theory and permanent equipment still exist; therefore, these get the present tense: “The purpose of this report is…” “Bragg’s Law for diffraction is …” “The scanning electron microscope produces micrographs …”

Example good introduction

Method • Use past tense • Can be in flowchart and sentences (both or sentence only)

Example of method 2 ml of ammonia buffer was added into the conical flask

Result • summarize the data from the experiments without discussing their implications. • The data should be organized into tables, figures, graphs, photographs, and so on. • Calculation is included in this part

Result • All figures and tables should have descriptive titles and should include a legend explaining any symbols, abbreviations, or special methods used. • Figures and tables should be numbered separately and should be referred to in the text by number, for example: -Figure 1 shows that the activity decreased after five minutes. -The activity decreased after five minutes (fig. 1).

Result: Example of Graph

Discussion • Most important part • Explain. Analyse. Interpret. • Reaction Equation and mechanism must be included • Explain the mechanism

Discussion • Compare expected results with those obtained. -If there were differences, how can you account for them? Saying “human error” implies you’re incompetent. -Be specific; for example, the instruments could not measure precisely, the sample was not pure or was contaminated, or calculated values did not take account of friction.

Discussion • Analyze experimental error. - Was it avoidable? Was it a result of equipment? - If an experiment was within the tolerances, you can still account for the difference from the ideal. If the flaws result from the experimental design explain how the design might be improved.

Discussion • Explain your results in terms of theoretical issues. - Usually you will have discussed these in the introduction. In this section move from the results to theory. How well has theory been illustrated?

Discussion • Relate results to your experimental objective(s).

Discussion

Conclusion • Answer back the objective of the experiment • Include the key finding in the experiment
