The major product of the following reaction is:
$Ph-CH(CH_3)-CH(Br)-CH_2-CH_2-Br \xrightarrow{KOH \text{ (alc, excess)}, \Delta} ?$

Consider the reaction: $CH_3-CH_2-CH(F)-CH_3 \xrightarrow{CH_3O^{-}} X$. The alkene formed in major amount is:

The relative reactivity of
$(I)$ Benzyl chloride
$(II)$ $p$-methoxy benzyl chloride
$(III)$ $p$-Nitrobenzyl chloride
Towards $S_N^1$ reaction follows the order

What happens when $CCl_4$ is treated with $AgNO_3$?

Arrange the following halides in the decreasing order of their reactivity towards $S_{N^1}$ reaction.
$(I) \ CH_3CH_2CH_2Cl$ $(II) \ CH_2 = CH - CH(Cl)CH_3$
$(III) \ CH_3CH_2CH(Cl)CH_3$
