Elimination reactions (especially \beta -elimination) are as common as the nucleophilic substitution reaction in case of alkyl halides. Specify the reagents used in both cases.

<p><span data-teams="true">This is a short answer type question as classified in NCERT Exemplar</span></p><p>Nucleophilic substitution and elimination (β-elimination) reactions are both possible with alkyl halides.</p><p>Although, with the appropriate reaction conditions and reagent selection, a specific product can be produced. In most cases, the elimination reaction is best suited to strong and bigger bases, as well as high temperatures. The substitution reaction, on the other hand, is best for weaker and smaller bases at lower temperatures.</p><p>CH₃CH₂Br+alc.KOH<img src="https://images.shiksha.com/mediadata/images/articles/1747110396phpHrfDEp.jpeg" alt="" width="51" height="23"> KCH₂=CH₂&nbsp;+ HBr</p><p>CH₃CH₂Br + aqKOH→CH₃CH₂OH + KBr</p>
