ASSERTION (A): The +M effect of -F is stronger than that of -I, making fluorine the most o/p directing of all halogens. REASON (R): Fluorine has the smallest atomic radius among halogens, allowing better p-orbital overlap with the ring pi system for +M donation.

ASSERTION (A): Fluorobenzene is less reactive toward EAS than chlorobenzene. REASON (R): The -I effect is strongest for fluorine (most electronegative), making it the most deactivating halogen.

ASSERTION (A): The arenium ion in EAS is more stable than the sigma complex formed in electrophilic addition to alkenes. REASON (R): The arenium ion is resonance-stabilized over three ring carbons and is the penultimate step before rearomatization.

In the bromination of toluene with $Br_{2}$/$FeBr_{3}$, the kinetic product distribution is approximately 58% ortho, 38% para, 4% meta. If temperature is raised significantly, which change is expected?

How does the +M effect of -Cl direct to ortho/para in chlorobenzene despite the ring being electron-deficient overall?
