The reaction shown above is a Baeyer-Villiger rearrangement of an asymmetric ketone with magnesium monoperoxyphthalate hexahydrate (in the drawing,$Mg^{+2}$ is omitted for clarity). Identify the major product.

$HCHO$ (more reactive towards oxidation) + $CH_3CHO \xrightarrow{Conc. NaOH}$ Find out the products of the reaction.

Identify the major product '$A$' formed in the following reaction:
$CH_3COCH_2CH(CH_3)CH_2Br \xrightarrow[(ii) H_2O]{(i) Mg} 'A'$

Reactant of Column-$I$ when reacted with acetaldehyde in the presence of $H^{+}$ gives the product given in Column-$II$ and their names are given in Column-$III$. Match the reactants in Column-$I$ with the products in Column-$II$ and their names in Column-$III$.

Column-$I$ (Reagent)	Column-$II$ (Product) and Column-$III$ (Name)
$A$. Ammonia $(NH_{3})$	$i$. $CH_{3}CH=NCH_{3}$; $m$. Acetaldehyde hydrazone
$B$. Amine $(CH_{3}NH_{2})$	$ii$. $CH_{3}CH=NNH_{2}$; $n$. Acetaldehyde oxime
$C$. Hydroxyl amine $(NH_{2}OH)$	$iii$. $CH_{3}CH=NH$; $o$. Acetaldehyde imine
$D$. Hydrazine $(NH_{2}NH_{2})$	$iv$. $CH_{3}CH=NOH$; $q$. Acetaldehyde methyl imine

How many aldol products are possible (excluding stereoisomers) for the following reaction?
$CH_3-CHO + CH_3-CH_2-CHO \xrightarrow{OH^-/H_2O}$
