distinguish between methylethylketone, acetaldehyde, diethylketone, and propanal
All commonly undergo Nucleophilic Addition Reaction
Acetaldehyde and propanal gives positive test towards Tollens, Fehlings and Benedict's while ketones gives negative test
Methyl ethyl ketone and acetaldehyde gives haloform reaction
distinguish between methylethylketone, acetaldehyde, diethylketone, and propanal
Write all possible products from aldol reaction between: Butanal and Propanal Formaldehyde and Acetaldehyde What is the product for aldol condensation in reaction 7(b) Write reaction for the synthesis of 3-Metyl-2-cyclohexenone using aldol condensation reaction.
What chemical test(not physical properties) can be used to distinguish between: - Benzaldehyde and Acetaldehyde - Benzaldehyde and Acetone Possible tests: Sodium Fusion, Equivalence Weight, Oxidation Test, Chromic Acid Test, Tollens' Test, Iodoform Test.
- Suggest two different chemical tests that would help distinguish between the following pairs of compounds. State what you would do and what you would see: a) benzaldehyde and benzyl alcohol b) 2-pentanone and 3- pentanone c)propanal and diethyl ether d) acetophenone and phenylacetaldehyde e)Propanal and propanoic acid -Suggest an IR frequency that would help distinguish between each pair of the previous compounds

please answer #5
5. Which type of spectroscopy (IR, 'H NMR, and/or "C NMR) would be good to distinguish between propanal and propanoic acid? State what you would observe for each compound in each type of spectroscopy and whether that type of spectroscopy would be a good way to distinguish between the two compounds.
Discuss a chemical test that distinguishes both Propanal and acetophenone from other functional groups and two tests that distinguish propanal from acetophenone (write all the reactions involved in these tests).
