An organic compound '$\mathrm{A}$' with molecular formula ${\mathrm{C}}_{17}{\mathrm{H}}_{36}{\mathrm{O}}_6$ is neither reduced by ${\mathrm{LiAlH}}_4$ nor reacts with $\mathrm{Na}$. But '$\mathrm{A}$', on hydrolysis in strong acidic medium, gives $\text{'}\mathrm{B}\text{'} \left({\mathrm{C}}_{11}{\mathrm{H}}_{24}{\mathrm{O}}_6\right)$ and other species. $1$ mole of $\mathrm{B}$ with an excess of $\mathrm{Na}$ gives $3$ moles of ${\mathrm{H}}_2$ gas. $\mathrm{B}$ is unreactive to ${\mathrm{HIO}}_4$ oxidation. $\mathrm{B},$ when reacted with an excess of red $\mathrm{P}$ and $\mathrm{HI}$, gives undecane as an organic product. The structures of $\mathrm{A}$ and $\mathrm{B}$ are:

An aromatic compound $\left(\mathrm{A}\right)$ with molecular formula ${\mathrm{C}}_{14}{\mathrm{H}}_{20}{\mathrm{O}}_4$ with ${\mathrm{HIO}}_4$ gives $2$ moles of $\left(\mathrm{B}\right) {\mathrm{C}}_2{\mathrm{H}}_4\mathrm{O}$ and
mole of $\left(\mathrm{C}\right) {\mathrm{C}}_{10}{\mathrm{H}}_8{\mathrm{O}}_2.$ Both $\left(\mathrm{B}\right)$ and $\left(\mathrm{C}\right)$ give yellow precipitate with ${\mathrm{I}}_2/{\mathrm{OH}}^{-}.\left(\mathrm{C}\right)$ with ${\mathrm{I}}_2/{\mathrm{OH}}^{-}$ gives $\left(\mathrm{D}\right) {\mathrm{C}}_8{\mathrm{H}}_6{\mathrm{O}}_4$
and $2$ moles of ${\mathrm{CHI}}_3$. Compound $\left(\mathrm{D}\right)$ with red $\mathrm{P}$ and $\mathrm{HI}$ gives $\left(\mathrm{E}\right)$. Which has zero dipole moment? Give the structures of $\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{D}$ and $\mathrm{E}$.

An optically active alcohol $\mathrm{A} \left({\mathrm{C}}_6{\mathrm{H}}_{10}\mathrm{O}\right)$ absorbs two moles of hydrogen per mole of $\mathrm{A}$. Upon catalytic hydrogenation, gives a product $\mathrm{B}$. The compound $\mathrm{B}$ is resistant to oxidation by ${\mathrm{CrO}}_3$ and does not show any optical activity. Deduce the structures of $\mathrm{A}$ and $\mathrm{B}.$

An unknown hydrocarbon $\left(\mathrm{A}\right)$, with formula ${\mathrm{C}}_6{\mathrm{H}}_{12}$, react with $1$ molar equivalent of ${\mathrm{H}}_2$ over a palladium catalyst. Hydrocarbon $\mathrm{A}$ also react with ${\mathrm{OsO}}_4$ to give a diol $\left(\mathrm{B}\right)$. When oxidized with ${\mathrm{KMnO}}_4$ in acidic solution, '$\mathrm{A}$' gives two fragments. One fragment is propanoic acid and other fragment is a ketone $\left(\mathrm{C}\right)$. What are the structures of $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ ?
