Read the  passage given below and answer the following questions:

Alkyl/Aryl halides may be classified as mono, di or polyhalogen compounds depending on one, two or more halogen atoms in their structures. Alkyl halides are prepared by free radical halogenation of alkanes, addition of halogen acids to alkenes and replacement of –OH group of alcohols with halogens using phosphorus halides, thionyl chloride or halogen acids. Aryl halides are prepared by electrophilic substitution to arenes.

Read the passage given below and answer the following questions:Alkyl/...

Reactivity towards β-elimination reaction:

- 2-Bromopentane: This compound is least reactive towards β-elimination reaction as it is a primary alkyl halide, and primary alkyl halides typically undergo substitution reactions rather than elimination reactions.

- 1-Bromopentane: This compound is more reactive towards β-elimination reaction compared to 2-Bromopentane as it is a secondary alkyl halide. Secondary alkyl halides are more prone to elimination reactions due to the stability of the carbocation intermediate formed during the reaction.

- 2-Bromo-2-methylbutane: This compound is the most reactive towards β-elimination reaction among the given options as it is a tertiary alkyl halide. Tertiary alkyl halides undergo β-elimination reactions readily to form alkenes due to the stability of the resulting alkene product.

Therefore, 2-Bromo-2-methylbutane is the compound most reactive towards β-elimination reaction among the provided options.
