Chemistry - STEREO ISOMERISM Question with Solution | TestHub

An optically active organic compound $\mathrm{A}\left({\mathrm{C}}_{10}{\mathrm{H}}_{14}{\mathrm{O}}_2\right)$ does not form a salt with aqueous NaOH and does not decolourise bromine water. However, it releases methane gas when treated with ${\mathrm{CH}}_3\mathrm{MgBr}$. When A is heated with HI , followed by treatment with KOH and then acidification, an optically active compound $\mathrm{B}\left({\mathrm{C}}_8{\mathrm{H}}_{10}{\mathrm{O}}_2\right)$ is obtained. On oxidation with PCC, compound B gives compound $\mathrm{C}\left({\mathrm{C}}_8{\mathrm{H}}_8{\mathrm{O}}_2\right)$. Compound C gives a positive iodoform test, is optically inactive, and produces only one monochioro derivative $\mathrm{D}\left({\mathrm{C}}_8{\mathrm{H}}_7{\mathrm{O}}_2\mathrm{Cl}\right)$ when treated with ${\mathrm{Cl}}_2/{\mathrm{FeCl}}_3$.

Which of the following options correctly represent the identities of the compounds?
