Interpretation Introduction

Interpretation:

The product of the reaction has to be identified and the stereochemistry has to be specified.

Concept introduction:

S_N1 reaction:

The alcohol is reaction with acids like hydrochloric acid or hydrobromic acid which yield the corresponding carbocation intermediate, this carbocation intermediate undergoes substitution reaction which yields the corresponding substitution product.

Tertiary alcohols undergo substitution very fast than the secondary alcohols because tertiary carbocation is more stable than the secondary carbocation than the primary carbocation. Primary alcohol is less stable therefore it won't undergo S_N1substitution reaction.

E₁ elimination:

Alkyl halide forms carbocation by the removal of bromine followed by the abstraction of the proton from the β-carbon atom in two steps which leads to the product as an alkene.

Given information:

The given compound is shown below,
