Match List-$I$ with List-$II$.
$1$-Bromopropane is reacted with reagents in List-$I$ to give products in List-$II$.

List-$I$ (Reagent)	List-$II$ (Product)
$A$. $KOH$ (alc)	$I$. Nitrile
$B$. $KCN$ (alc)	$II$. Ester
$C$. $AgNO_2$	$III$. Alkene

What is obtained when toluene is chlorinated in the presence of light and then heated with aqueous $NaOH$?

What will be the product in the following reaction?
$1$-chloro-$1$-methylcyclohexane $\xrightarrow{H_2O}$ ?

$C_6H_{13}Br + OH^{-} \to C_6H_{13}OH + Br^{-}$ is an example of

$CH_3-CH_2-Br + Nu^{\Theta} \rightarrow CH_3-CH_2-Nu + Br^{\Theta}$
The decreasing order of the reaction rate with nucleophile $Nu^{\Theta}$ is $Nu^{\Theta} = (I) PhO^{\Theta}; (II) CH_3COO^{\Theta}; (III) OH^{\Theta}; (IV) CH_3O^{\Theta}$
