An alkyl halide may be converted into an alcohol by

Which of the compounds will react faster in an $S_N1$ reaction?
$CH_3-CH_2-Cl$ and $C_6H_5-CH_2-Cl$

Which of the following compounds will react with $Na$ to form $4,5-$diethyloctane?

An alkene $X$ $(C_4H_8)$ on reaction with $HBr$ gave $Y$ $(C_4H_9Br)$. Reaction of $Y$ with benzene in the presence of anhydrous $AlCl_3$ gave $Z$,which is resistant to oxidation with $KMnO_4-KOH$. What are $X, Y, Z$ respectively?
