Answer: Higher.
- A Much lower
- B Similar
- C The same
- D Higher
Correct answer: D. Higher
Explanation: Haloalkanes have higher boiling points than comparable alkanes because C-X dipoles contribute stronger intermolecular attractions.
SN2 proceeds in a single step with backside attack and inversion of configuration, while SN1 forms a planar carbocation intermediate first, leading to racemisation.
Concept context
Study carbon-halogen compounds: how they are made, how they react via SN1/SN2 and elimination, their stereochemistry, and their environmental impact.
