Explain two differences between haloalkanes and haloarenes.

(N/A) The two main differences between haloalkanes and haloarenes are as follows:
$1$. Structure: In haloalkanes,the halogen atom is bonded to an $sp^3$ hybridized carbon atom of an alkyl group. In haloarenes,the halogen atom is directly bonded to an $sp^2$ hybridized carbon atom of an aromatic ring.
$2$. Reactivity towards Nucleophilic Substitution: Haloalkanes are generally more reactive towards nucleophilic substitution reactions compared to haloarenes. Haloarenes show low reactivity due to resonance effects,which give the $C-X$ bond partial double bond character,and the instability of the phenyl cation.
