Describe an experiment you will carry out and the result that you will expect to distinguish between the following:
Ethanol (Alcohol)
1-bromoethane (Halogenoalkane)
Ethanal (aldehyde)
Carry out your experiment and identify substances X, Y and Z. The unknown substances provided are Ethanol, 1-bromoethane and Ethanal.
With the molecular formula C4H8O , I ask you to draw 3 molecules: an aldehyde, a ketone and an enol.For each molecule, you must:
a) Complete detailed Lewis structure;b) Make the 3D structure respecting the connection angles;c) Determine which intermolecular interactions are present if you glue 2 twin molecules together (2 aldehydes together, 2 ketones together, 2 enols together, therefore 3 situations to analyze).
A certain hydrocarbon had the molecular formula C18H30 and contained two triple bonds. Ozonolysis gave CH₂(CH₂)CO₂H and HO₂CCH₂CH₂CO₂H as the
only products. Draw a reasonable structure for this hydrocarbon.
