Why does the E2 reaction of 2-chloro-2-methylbutane with KOH and 1-propanol prefer 2-methyl-1-butane as its major product but when its reacted with Potassium Tert-Butoxide in Tert-Butyl Alcohol it prefers 2-methyl-2- butene as its major product?

What are the mechanisms and major/minor products when 2-Chloro-2-Methylbutane reacts with A.) Potassium Hydroxide in 1-propanol+Heat B.)Potassium tert-butoxide in tertbutyl alcohol+heat I know they proceed via E2 reaction mechanism but need help figuring out the steps and the major and minor products. Also if you could offer a brief explanation of why the mechanism reacts the way it does I would really appreciate it. Thank you!

Consider the synthesis of tert-amyl chloride (2-chloro-2-methylbutane) from 2-methyl-2-butanol and HCl which has SN1 reaction. Explain if a SN1 reaction would occur if the following(below) was changed. If an SN1 does occur, then state the IUPAC name of the product formed and compare the rate of reaction to the rate of the original reaction .

A student was planning to synthesize 2-chloro-3-methylbutane from 3-methyl-2-butanol using concentrated HCl, similar to the reaction you did. When the experiment was carried out, the product isolated was 2-chloro-2-methylbutane. Explain these results by showing a plausible mechanism for the formation of 2-chloro-2-methylbutane under these reaction conditions. (Hint: it is an SN1 reaction, but think about what can happen to the carbocation intermediate that we learned about in lecture to cause that product to form.)
