There are mechanisms that can be used to explain the results.
Under base-catalyzed conditions, several molecules of propylene oxide can react.
The base-catalyzed formation of the following trimer is proposed.
An acid-catalyzed reaction was carried out using a solvent.
The higher-boiling fraction was recovered when the 2-methoxyethanol was redistilled.
The mass spectrum of this fraction showed the weight.
The IR and NMR spectrums are shown here.
Determine the structure of this compound and propose a mechanism for its formation.
There is a molecule of two different colors.
Thelysis of propylene oxide gives another molecule.
The enantiomers of propylene oxide can be drawn.
There is a compound of molecular formula C8H O.

Propose a way to do something.
The functional groups have oxygen in them.
The number of stereoisomers can be calculated using the number of chiral centers.
In 2012 a group led by Professor Masayuki Satake of the University of Tokyo reported the isolation and structure determination of a toxin from a marine bloom that decimated the fish population off the New Zealand coast in 1998.
The structure shown below, named Brevisulcenal-F, is the result of extensive mass spectrometry and NMR experiments.
This structure has the record for the largest number of fused rings.
