Among the following,

the compounds which can be reduced with formaldehyde and conc. aq. $\mathrm{KOH},$ are:

The compound $\mathrm{X}$ in the following reaction scheme:

 is:

An organic compound $\mathrm{X}$ with molecular formula ${\mathrm{C}}_{11}{\mathrm{H}}_{14}$ gives an optically active compound on hydrogenation. Upon ozonolysis, $\mathrm{X}$ produces a mixture of compounds $-\mathrm{P}$ and $\mathrm{Q}.$ Compound $\mathrm{P}$ gives a yellow precipitate when treated with ${\mathrm{I}}_2$ and $\mathrm{NaOH}$ but does not reduce Tollen's reagent. Compound $\mathrm{Q}$ does not give any yellow precipitate with ${\mathrm{I}}_2$ and $\mathrm{NaOH}$ but gives Fehling's test. The compound $\mathrm{X}$ is:

The following transformation

can be carried out in three steps. The reagents required for these three steps in their correct order, are:

The major product formed in the following reaction is

In the reaction,

$\mathrm{X}$ and $\mathrm{Y}$ are :

In the following reaction,

$\mathrm{X}$ and $\mathrm{Y}$ are :

Acetophenone $\left({\mathrm{PhCOCH}}_3\right)$  reacts with perbenzoic acid to produce a compound $\mathrm{X}$. Reaction of $\mathrm{X}$ with excess ${\mathrm{CH}}_3\mathrm{MgBr}$ followed by treatment with aqueous acid predominantly produces
