Vedclass · Answer

(A) Step $1$: The partial hydrogenation of propyne $(CH_3-C \equiv CH)$ using $H_2$ over $Pd/C$ (Lindlar's catalyst or similar controlled hydrogenation) yields propene $(CH_3-CH=CH_2)$ as product $[A]$.Step $2$: Ozonolysis of propene $(CH_3-CH=CH_2)$ followed by reductive workup with $Zn/H_2O$ cleaves the double bond to form acetaldehyde $(CH_3CHO)$ as product $[B]$ and formaldehyde $(HCHO)$ as product $[C]$.Therefore,the correct sequence is $[A]: CH_3-CH=CH_2, [B]: CH_3CHO, [C]: HCHO$.

Identify products $[A]$,$[B]$,and $[C]$ in the following reaction sequence:
$CH_3-C \equiv CH$ $\xrightarrow{H_2, Pd/C} [A]$ $\xrightarrow[(ii) Zn, H_2O]{(i) O_3} [B] + [C]$
