Question

The unknown organic substances which were critric acid, acetone, urea, beazaldehyda, glycerol, and MTBE was done in an experiment- use this to answer the questions. (Note: there was no boiling point or melting point done in this experiment however their reaction to NaHCO3 was done)

 

a)Compare what you originally expected to identify at each step of the flow chart to what you identified. Were your predictions close to what you expected? Elaborate on your response.

b)What was the biggest challenge you faced in differentiating between the functional groups? Were there any that were difficult to distinguish between? Why?

b) Do you think this flow chart could be used to identify functional groups in a molecule that contains multiple different functional groups? Discuss. And how would you improve this flow chart procedure to better identify the organic compoun?

Step 2: Solubility
Soluble in Water: Likely a polar or ionic compound.
Soluble in Octane: Likely a nonpolar organic
compound
Step 3: pH
•Acidic: Could be a carboxylic acid, phenol, or other
acidic compound
Neutral: Could be an alcohol, ester, or other neutral
compound
Basic: Could be an amine or other basic compound.
Step 4: Tollens Test
Positive: Indicates the
of
presence an aldehyde.
Negative: Could be a ketone, alcohol, or other
functional
group.
Step 5: Odor
•Distinct Odor: Could be a volatile organic compound
with a characteristic smell.
No Odor: Could be a non-volatile or odorless
compound.

Freezes in Ice Bath: Indicates a relatively high
melting point.
Does not Freeze: Indicates a lower melting point
or a liquid at room temperature.
