Final answer:
The dehydration of 2-methyl-2-butanol follows an E1 mechanism, and the most stable alkene produced is typically the major product according to Zaitsev's rule.
Step-by-step explanation:
The acid-catalyzed dehydration of 2-methyl-2-butanol typically involves a mechanism where a carbocation intermediate is formed.
This reaction is an E1 mechanism, not an E2 mechanism as suggested in option (c).
During the dehydration process, multiple alkenes may form due to the different possibilities of proton elimination from the carbocation.
However, the major product is usually the most stable alkene, which follows Zaitsev's rule, suggesting that the most substituted alkene is the major product.
Therefore, if 'compound 6' is the most substituted alkene that can form from the dehydration of 2-methyl-2-butanol, option (e) 'compound 6 is the most stable alkene produced' would be correct.
However, without the specific details of the mechanism provided, confirming whether option (a), '2-methyl-1-butene is also produced by the dehydration' is correct, or option (b), 'the curved arrows shown in the mechanism are drawn correctly', cannot be determined as true without the visualization of the actual mechanism.
Option (d), 'the curved arrows shown in the mechanism are not drawn correctly' is in direct contradiction to option (b) and also cannot be confirmed without looking at the provided mechanism.
