WebMar 1, 2024 · Elimination of the OH group usually requires protonation of oxygen, which requires an acidic medium. A good solution to the given problem would be to add HBr without peroxide, which will give SN$_2$ (no rearrangement, i.e. no cation shift) and give us $\ce{CH3CH2CH2CH2Br}$. Then, add $\ce{(CH3)3COK/(CH3)3COH}$ to get but-1-ene.
