Chemistry · JEE | Haloalkanes and Haloarenes

What causes competition between substitution (\( \text{S}_N1/\text{S}_N2 \)) and elimination when an alkyl halide reacts with a base or nucleophile?

A
Constant temperature and atmospheric pressure exclusively
B
Only the molar concentration of the halogen compound
C
Only the polarity and dielectric constant of the dry ether solvent
D
Nature of alkyl halide, strength and size of base/nucleophile, and reaction conditions

View Answer & Solution

Correct answer · Option D

Nature of alkyl halide, strength and size of base/nucleophile, and reaction conditions

The preferred route between substitution and elimination depends on the nature of the alkyl halide, base strength and size, and reaction conditions.
