Provide the following electrophilic substitution reactions of aryl halides:
$(i)$ Halogenation
$(ii)$ Nitration
$(iii)$ Sulphonation
$(iv)$ Friedel-Crafts reaction

(N/A) $(i)$ Halogenation: Chlorobenzene reacts with $Cl_2$ in the presence of anhydrous $FeCl_3$ to form $1,4$-dichlorobenzene (major) and $1,2$-dichlorobenzene (minor).
$(ii)$ Nitration: Chlorobenzene reacts with conc. $HNO_3$ and conc. $H_2SO_4$ to form $1$-chloro-$4$-nitrobenzene (major) and $1$-chloro-$2$-nitrobenzene (minor).
$(iii)$ Sulphonation: Chlorobenzene reacts with conc. $H_2SO_4$ upon heating to form $4$-chlorobenzenesulphonic acid (major) and $2$-chlorobenzenesulphonic acid (minor).
$(iv)$ Friedel-Crafts reaction: Chlorobenzene undergoes alkylation (with $CH_3Cl$ and anhydrous $AlCl_3$) or acylation (with $CH_3COCl$ and anhydrous $AlCl_3$) to yield ortho and para substituted products,with the para-isomer being the major product.
