Identify product [A],[B] and [C] in the following reaction sequence. {\CH}_3- {\C} \equiv {\CH} \xrightarrow[\H_2]{} ^{{\Pd} \/ {\C}} [ {\A}] \xrightarrow[\text{ (ii) ]{} {\Zn}, {\H}_2 {\O}} ^{\text{ (i) } {\O}_3}[ {\B}]+[ {\C}] [28 Jan 2025 Shift 2]

Correct Answer is : [A]:CH3−CH=CH2,[B]:CH3CHO,[C] : HCHO

[ {\A}]: {\CH}_3 {\CH}_2 {\CH}_3,[ {\B}]: {\CH}_3 {\CHO},[ {\C}]: {\HCHO}

[ {\A}]: {\CH}_2= {\CH}_2,[ {\B}] : H_3C^{||↖{O}}-C-CH_3, [C]: HCHO

[ {\A}]: {\CH}_3- {\CH}= {\CH}_2,[ {\B}]: {\CH}_3 {\CHO},[ {\C}] : HCHO

[ {\A}]: {\CH}_3- {\CH}= {\CH}_2,[ {\B}]: {\CH}_3 {\CHO}, [C] : {\CH}_3 {\CH}_2 {\OH}
