Chapter 10, Problem 40P

(a)

Interpretation Introduction

Interpretation:

Reactant which undergoes elimination reaction more rapidly is to be identified.

Concept Introduction:

Elimination from a tertiary alkyl halide leads to more substituted product from secondary alkyl halide.  Same way elimination from a secondary alkyl halide leads to more substituted alkene than does elimination from primary alkyl halide.

Relative relativities of alkyl halide in an E₂ reaction is,

$\text{3°> 2°> 1°}$

(b)

Interpretation Introduction

Interpretation:

Reactant which undergoes elimination reaction more rapidly is to be identified.

Concept Introduction:

Elimination from a tertiary alkyl halide leads to more substituted product from secondary alkyl halide. Same way elimination from a secondary alkyl halide leads to more substituted alkene than does elimination from primary alkyl halide.

Relative relativities of alkyl halide in an E₂ reaction is 3⁰ > 2⁰ > 10
