(a)
Interpretation:
More reactive
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
(b)
Interpretation:
More reactive alkyl halide in the given pair when reacts in an E2 reaction with hydroxide ion has 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.
(c)
Interpretation:
More reactive alkyl halide in the given pair when reacts in an E2 reaction with hydroxide ion has 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.
