Complete the following reactions:
$(1)$ $CH_3CH_2CH_2CH_2Cl + H_2 \xrightarrow{Zn, H^{+}}$
$(2)$ $CH_3CH_2CH_2CH_3 \xrightarrow[HCl, \Delta]{Anhy. AlCl_3}$

(N/A) $(1)$ The reaction of $1$-chlorobutane with $H_2$ in the presence of $Zn, H^{+}$ is a reduction reaction that yields $n$-butane:
$CH_3CH_2CH_2CH_2Cl + H_2 \xrightarrow{Zn, H^{+}} CH_3CH_2CH_2CH_3 + HCl$
$(2)$ The reaction of $n$-butane with anhydrous $AlCl_3$ and $HCl$ at high temperature is an isomerisation reaction that yields $2$-methylpropane (isobutane):
$CH_3CH_2CH_2CH_3 \xrightarrow[HCl, \Delta]{Anhy. AlCl_3} CH_3-CH(CH_3)-CH_3$
