Methoxyethane on reaction with hot concentrated $HI$ gives

Which one of the following reactions does not yield an alkyl halide?

When ether is reacted with $O_2$,it undergoes explosion due to the formation of:

Which of the following will be obtained by keeping ether in contact with air for a long time?

$A$ mixed ether $(P)$,when heated with excess of hot concentrated hydrogen iodide,produces two different alkyl iodides which when treated with aqueous $NaOH$ give compounds $(Q)$ and $(R)$. Both $(Q)$ and $(R)$ give a yellow precipitate with $NaOI$. Identify the mixed ether $(P)$:

Match the products of the reaction with anisole in Column-$I$ with the reagents in Column-$II$. Find the correct reagent for the product in Column-$I$ from Column-$II$.

Column-$I$ (Product)	Column-$II$ (Reagent)
$A$. Mainly $p$-bromoanisole	$i$. Anhydrous $AlCl_3$,$CH_3COCl$
$B$. $4$-nitroanisole	$ii$. $CH_3Cl$,anhydrous $AlCl_3$ in $CS_2$
$C$. $4$-methoxytoluene	$iii$. $Br_2$ in ethanoic acid
$D$. $4$-methoxyacetophenone	$iv$. Mixture of conc. $H_2SO_4$ and $HNO_3$
