What alkyl halide forms 3-methyl-but-1-ene as the only product?

1-Bromo-3-methylbutane

Explanation:

Alkenes are being synthesized by using different starting materials (alcohols, alkyl halides, aldehydes e.t.c) via differenr reactions.

Among these reactions one of the important class of reactions utilized for alkene formation are the Elimination reactions of Alkyl Halides either via E1 or E2 mechanism.

In given statement the starting material which can result in the formation of only 3-Methyl-but-1-ene is 1-Bromo-3-methylbutane. Also, the reaction is attached as below.
