Question

(a) Haloalkanes give β-elimination. 

(i) Prepare CH₂ = CH₂ from CH₃ – CH₂ X and alchoholic KOH. 

(ii) Give the major product of the β-elimination of Name the related rule.

(b) In the following pairs of halogen compounds which would undergo S_N2 reaction faster? Justify.

Answer 1

It is primary halide and therefore undergoes S_N2 reaction faster.

An iodide is a better leaving group because of its large size. It will be released at a faster rate in the presence of attacking nucleophile.
