Identify product [A], [B] and [C] in the following reaction sequence. CH_3- C ≡ CH →[ H_2] Pd / C [ A ] →[ (ii) Zn, H_2 O ] (i) O_3 [ B ]+[ C ]
Identify product [A], [B] and [C] in the following reaction sequence.
$$\mathrm{CH}_3-\mathrm{C} \equiv \mathrm{CH} \xrightarrow[\mathrm{H}_2]{\mathrm{Pd} / \mathrm{C}}[\mathrm{~A}] \xrightarrow[\text { (ii) } \mathrm{Zn}, \mathrm{H}_2 \mathrm{O}]{\text { (i) } \mathrm{O}_3}[\mathrm{~B}]+[\mathrm{C}]
$$
