Interpretation Introduction

Interpretation: From two stereoisomers of 1-tert-butyl-4-chloro-cyclohexane, one of them will react with sodium ethoxide by the ${\text{E}}_{\text{2}}^{}$ process $500$ times faster than the other isomer. The isomer that reacts faster is to be interpreted.

Concept introduction:

On the basis of the presence and strength of nucleophiles, halo-alkanes show competition between substitution and elimination. Elimination reaction can also proceed by ${\text{E}}_{\text{1}}$ and ${\text{E}}_{\text{2}}^{}$ process.

The elimination reaction of haloalkanes involves the halide ions as the leaving group mainly and forms alkene as the product.
