This image highlights the oxidation process of ethylene glycol fairly well
( Taken from Ethylene glycol: properties, synthesis, and applications )
Since it has little tendency to evaporate, unless it is kept in direct sunlight, it would probably oxidize to a mixture of the above liquid compounds (glyoxal, glyoxalic acid) and not directly to water. If it is ...

The most important simplified criteria for the numbering in such cases are:
lower locants for the principal characteristic group that is expressed as suffix
lower locants for multiple bonds
lower locants for prefixes
lower locants for substituents cited first as a prefix in the name
The corresponding actual wording in the current version of Nomenclature of ...

Alumina absorbs water to give aluminium oxide hydroxide, a solid which removes the water from the reaction environment.
According to this paper from the Journal of Materials Science here
Aluminium oxide exists in several forms which on addition of water give a complex range of oxide-hydroxide; boehmite, bayerite and gibbsite.

To reason about the kinect reaction you must consider the mechanism of the reaction. Honestly I can't say much about this reaction specificaly since the oxidation mechanism by KMnO4 is considerably complex and not much studied probably until graduate courses. I can say, however, that you can't reason about the reaction kinectics under the consideration of ...

Here the issue in question is about rate. Of course, in a real life scenario, both reactions probably take place, the question is which reaction is faster?
Well, looking at the reactants here, you are having a strong acid. The hydroxy group is way more basic/nucleophilic than the double bond simply due to electronic effects. Hence, the Sn1 substitution is ...

My suspicion is that the resonance structures accessible to the allylic carbocation provide a lower energy state than the formation of the C--H single bond and the isolated carbocation that your expected pathway would require.
In order of reactivities, you are right to think that the alcohol is the controlling factor because of its pKa. Under acidic ...
