Write the structures of the products of the following reactions:
$(i)$ $CH_3-CH=CH_2 \xrightarrow{H_2O/H^+}$
$(ii)$ (See image)
$(iii)$ $CH_3-CH_2-CH(CH_3)-CHO \xrightarrow{NaBH_4}$

(N/A) $(i)$ $CH_3-CH=CH_2$ (Propene) $\xrightarrow{H_2O/H^+}$ $CH_3-CH(OH)-CH_3$ (Propan$-2-$ol)
$(ii)$ $NaBH_4$ selectively reduces the ketone group to a secondary alcohol while leaving the ester group intact. The product is Methyl ($2$-hydroxycyclohexyl) ethanoate.
$(iii)$ $CH_3-CH_2-CH(CH_3)-CHO$ ($2$-Methylbutanal) $\xrightarrow{NaBH_4}$ $CH_3-CH_2-CH(CH_3)-CH_2OH$ ($2$-Methylbutan$-1-$ol)
