Identify `Z + Y` in the following synthetic scheme and write their structures. Explain the formation of labelled formaldehyde `(H_2 C^(**) O)` as one of the products when compound `(Z)` is treated with `HBr` and subsequently ozonolysed. Take `C^(**)` as carbon in the entire scheme.
`BaC^(**) O_3 + H_2 SO_4 rarr X(C^(**) = C^(14))`
.

Identify (A) to (F) and mark the C^(**) carbon in the entire scheme Ca overset ** C O_3 + H_2 SO_4 rarr (A) (gas) [C^** deno tes C^14] . .

Identify X in the following synthetic scheme and write their structures. BaCO_(3)+H_(2)SO_(4)rarrX_((g))(C "denotes" C^(14))

Identify X, Y and Z in the following synthetic scheme and write their structures. The product Z when treated with HBr gives compound A which on reductive ozonolysis gives formaldehyde as one of the product. Deduce the entire scheme.

Identify (X), (Y) and (Z) in the following synthetic scheme and write their structures. CH_(3)CH_(3) -C-=Choverset(i) NaNH_(2)underset(CH_(3)CH_(2)Br) to (X) overset(H_(2)//Pd-BaSO_(4))to (Y) overset("alkaline"KMnO_(4))to(Z) Is the compound (Z) optically active? Justify your answer.

A compound 'X' (C_(2)H_(4)O) on oxidation gives 'Y' (C_(2)H_(4)O_(2)) . The compound 'X' undergoes haloform reaction. Write the structure of 'X' and 'Y'. Name the product when 'X' is treated with NaOH .
