Why is the E1 not a likely mechanism when 1-chloropentane is heated in ethanol?

Wolff - Kishner reduction of 7-methyl-2-cycloheptenone produces 3-methylcycloheptene, not 4-methylcycloheptene. Write the reaction and its mechanism. It is not necessary to write a mechanism for the formation of the hydrazone. ANSER MUST BE DRAWN! Thank you.

Treatment of the following stereoisomer of 1-bromo-1,2- diphenylpropane with sodium ethoxide in ethanol gives a single stereoisomer of 1,2-diphenylpropene. H3C H C6H5 H C6H5 Br ***I CH3CH₂O Na+ Draw the E2 elimination product of the reaction. Take into account that the starting stereochemistry affects the resulting double bond stereochemistry. CH₂CH₂OH Consider E/Z stereochemistry of alkenes. Do not show stereochemistry in other cases. • You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just draw one. Sn [F ?

One of the products that results when 1-bromo-2,2-dimethylcyclopentane is heated in ethanol is shown below. Propose a mechanism by which it is formed.
