Chemistry Drawing Question: Reaction Mechanism

The mechanistic arrow (see p. 32 of your lab manual) represents the movement of 2 electrons, which forms or breaks a bond. Mechanistic arrows move from -ve to +ve. e.g. from a lone pair of electrons, a bond (which is 2 electrons) or a -ve charge

Below is an incomplete reaction scheme for a generic acid-catalysed Fischer esterification.

Generally, your lab notes should contain the following:

• Name and student ID recorded.

• Experiment title and date recorded.

• Notes are written in pen.

• Method recorded in brief, including changes to experimental variables/conditions (if applicable).

• All results, data, and observations are recorded, and are neat and legible.

Conclusion

You should finish your report with a short statement commenting on what you achieved, and what your final result/s were (include formulas or names if appropriate!). Think of it as a spoiler for your whole lab report! Your conclusion should answer all parts of your aim. Don’t forget – you had two parts to this experiment.

For example:

If the aim is: Determine the concentration of Vitamin C in a fruit juice via a redox titration against N-bromosuccinimide.

The conclusion might be: Berri orange juice (2000 μL aliquots, in triplicate) was titrated against a 0.104 M solution of N-bromosuccinimide. The concentration of Vitamin C in the fruit juice was determined to be 55.0 mg/L.
