Question

Why is cyclohexyl chloride more reactive than chlorobenzene?

Answer 1

$\huge\mathfrak\red{HeyA..!}$

Hence chlorobenzene is more electronegative than cyclohexyl chloride. Therefore, the density of electrons C-Cl bond at chlorine atom is less in chlorobenzene than cyclohexyl chloride. Due to this polarity of the C-Cl bond decreases and hence dipole moment of chlorobenzene is lower than cyclohexyl chloride

Answer 2

in chlorobenzen after removing chlorine . cation is more stable due to resonance
