Which isomer of 1-bromo-4-tert-butylcyclohexane reacts faster when refluxed with potassium tert-butoxide?

Chemistry
1 answer:
grigory [225]3 years ago
7 0

Answer:

See explanation.

Explanation:

Since potassium tert-butoxide is a strong bulky base, we expect that an elimination reaction predominates.

This reaction is expected to occur by E2 mechanism. The cis isomer of  1-bromo-4-tert-butylcyclohexane is known to react faster by E2 mechanism because it fulfills the anticoplanar arrangement required for for E2 mechanism, where the leaving group and adjacent proton must be anti to each other and in the same plane. The trans isomer can not fulfill this requirement.

The images show two unrelated events occurring at separate times.
madreJ [45]

Event 1 is an example of a chemical reaction.

<u>Explanation:</u>

Whenever there is a chemical reaction, we can find that by means of a color change, formation of any gas, vapors, bubbles or any color or colorless precipitation, or by means of heat generation.

In the event 1 there is only a clear liquid in the beaker again it is added to a clear liquid in another beaker, forming an orange colored liquid , which shows that there is an occurrence of some chemical reaction.

So Event 1 is most likely an example of a chemical reaction.
