Module 1 Lab Report

I have attached the procedure/reading associated with the lab. I am attaching each section needed and within is exactly what each section must talk about/refer to. Must meet all requirements listed in each section.

INTRODUCTION:

Does the introduction contain the following?

• A one or two sentence description of the procedure
• The goal of or reason for the procedure and how success in reaching this goal will be determined
• Physical or chemical properties being exploited to transform the compound by reaction and collect and isolate the final product
• A brief discussion of how the 12 Principles of Green Chemistry were considered in the design of this procedure.
• A proposed mechanism for this reaction
• A mention of specialized equipment used to complete the procedure and confirm your predictions (Hot plates are not special equipment)

DETAILS AND OBSERVATIONS:

Does the observations section contain the following?

• A succinct and objective report of how the procedure was done in the lab written in paragraph form using past tense.
• Enough information that your teaching assistant could reproduce your work and achieve similar results
• Any time these instructions tell you to observe or record your observations, you should have a written observation describing what you saw ( tells you when to observe or record observation in the reading and what I observed is included below ) ( If it tells you to include the observation past part 3 because I didnt get that far just say what you should have observed if it was completed)
• Your pre-lab plan is already turned in. If your Details and Observations section looks too much like your pre-lab plan, then points will be deducted. Report the unique details (included below) of your experiment and anytime you deviated from the pre-lab plan.

*I have attached the pre-lab plan to ensure that this section does not look too much like it**

UNIQUE DETAILS:

• Part 1 – 6 drops of cyclohexanol = 0.160g, not 0.145g
• Part 1 – 4 drops of acetic acid
• Part 1 – pH<7, so added 3 more drops of acetic acid = pH of 2
• Part 1 – measured 2.5 mL of 6% sodium hypochlorite instead of 2.0.
• Part 1 – Observation after 6% sodium hypochlorite flask got warmer
• Oxidant check – When testing for oxidant present, this is what happened. Negative on first test. Added 5 more drops of hypochlorite solution, 5 more minutes in water, another negative test, added 0.5mL hypochlorite (10 drops), 5 more minutes in water, another negative test. added another 0.5mL hypochlorite (10 drops), 5 more minutes in water, another negative test, added 3 more drops, 3 more minutes in water, received a barely positive test (positive color on the rim/outline of the drop). Once positive it took 40 drops of bisulfite to get a negative test.
• Oxidant check – 1 drop of thymol blue indictator = turned solution blue automatically without 6M NaOH. added 2 drops of 6M NaOH just for safe measure.
• Part 2 – Temperature range during collection = 85 degree – 95 degree
• Part 3 – Added 0.104g or sodium chloride
• Part 3 – The pre-weighed Erlenmeyer flask weighed 17.096g.
• Part 3 – was able to extract with diethyl ether all 3 times, but lab ended before I could measure the mass of flask + product.

**EVERYTHING PAST THIS POINT IS ANOTHER STUDENT IN THE LAB’S RESULTS**NOT MY RESULTS**SPECIFY THAT THIS IS ANOTHER STUDENTS RESULTS**

• Part 3 – Another student’s pre-weighed Erlenmeyer flask weighed 16.7g and the flask + product weighed 17.3g
• Part 4 – Meltemp was set at 149 degree celcius
• Part 4 – Started to melt at 137 degree celcius and stopped at 149 degree celcius

CONCLUSION AND DISCUSSION :

Does the conclusions section contain the following based on your details, observations, and results?

• An answer to the claims and predictions you made in the introduction
• Discussion and comparison of the amount of hydroxide solution to acetic acid. Was the acid regenerated like a catalyst or did it seem to be consumed?
• A suggestion of what other specific alcohol(s) would you suggest be appropriate for oxidation to ketones with this procedure?
• Comparison of the melting point of the hydrazone derivative with the expected literature value and an evaluation of its purity
• Evaluation of how well this procedure adopted the 12 Principles of Green Chemistry
• Are all your conclusions based on the data you have collected? If you need or want to refer to another source, please include where that data can be found.
• Suggestions for future research that would add support for your prediction or further examine the physical and chemical properties exploited in this procedure

Discuss 2 of the following:

• Given access to an IR spectrophotometer, what specific additional information would you collect to support the claim that cyclohexanol was or was not oxidized by your procedure?
• Given access to an H-NMR spectrophotometer, what specific additional information would you collect to support the claim that cyclohexanol was or was not oxidized by your procedure?
• In the event that some cyclohexanol was oxidized beyond cyclohexanone and was completely oxidized to adipic acid, suggest a simple way to extract the acid from the desired product.
