(N/A) $(i)$ Cyclohexanol reacts with $SOCl_2$ to form chlorocyclohexane: $\text{Cyclohexanol} + SOCl_2 \rightarrow \text{Chlorocyclohexane} + SO_2 + HCl$.
$(ii)$ $4-\text{Ethylnitrobenzene}$ undergoes free radical bromination at the benzylic position: $4-\text{Ethylnitrobenzene} + Br_2 \xrightarrow{\text{heat or UV light}} 4-(1-\text{Bromoethyl})\text{nitrobenzene} + HBr$.
$(iii)$ $4-\text{Hydroxymethylphenol}$ reacts with $HCl$ to replace the alcoholic $-OH$ group: $4-\text{Hydroxymethylphenol} + HCl \xrightarrow{\text{heat}} 4-\text{Chloromethylphenol} + H_2O$.
$(iv)$ $1-\text{Methylcyclohexene}$ undergoes electrophilic addition with $HI$ following Markovnikov's rule: $1-\text{Methylcyclohexene} + HI \rightarrow 1-\text{Iodo}-1-\text{methylcyclohexane}$.
$(v)$ $CH_3CH_2Br$ reacts with $NaI$ in acetone (Finkelstein reaction): $CH_3CH_2Br + NaI \rightarrow CH_3CH_2I + NaBr$.
$(vi)$ Cyclohexene undergoes allylic bromination with $Br_2$ under heat or $UV$ light: $\text{Cyclohexene} + Br_2 \xrightarrow{\text{heat or UV light}} 3-\text{Bromocyclohexene} + HBr$.
