The following is a substitution reaction in which $-CN$ replaces $-Cl$:
$R-Cl \xrightarrow[\text{alcoholic}]{KCN, \Delta} R-CN + KCl$
To obtain propanenitrile,$R-Cl$ should be:

Which of the following compounds will produce the product shown in the image upon reaction with $NaCN$ via an $S_N2$ mechanism?

Consider the following reaction:
(Cyclohexyl)methyl chloride + $CH_3ONa$ $\rightarrow$ $1-$(methoxymethyl)cyclohex$-1-$ene.
The mechanism of the reaction will be:

Which of the following alkyl halides undergoes a substitution reaction according to the $S_{N}1$ mechanism?

Given below are two statements:
Statement $I$: $(CH_3)_3C-CH_2-Cl$ will undergo $S_N1$ reaction even though it is a primary halide.
Statement $II$: It will not undergo $S_N2$ reaction very easily even though it is a primary halide.
In the light of the above statements,choose the most appropriate answer from the options given below:
