NEETChemistryHaloalkanes and Haloarenes
What is the primary reason for the slow electrophilic substitution reactions in haloarenes compared to benzene?
Options
- ADecreased electron density at ortho- and para- positions
- BIncreased electron density at ortho- and para- positions
- CPresence of an electron-donating group
- DAbsence of a halogen atom
Correct answer
A. Decreased electron density at ortho- and para- positions
Step-by-step solution
Due to resonance, electron density increases more at ortho- and para- positions in benzene, leading to slower electrophilic substitution reactions in haloarenes.
