- ✓${C_2}{H_2}$
- B${C_2}{H_4}$
- C${C_3}{H_4}$
- D${C_4}{H_6}$
✓
Answer
Correct option: A.
${C_2}{H_2}$
a
(a) $\mathop {CH \equiv CH}\limits_{{\text{Ethyne}}} + {H_2}O\mathop {\xrightarrow{{HgS{O_4}}}}\limits_{{H_2}S{O_4}} \mathop {C{H_2} = CH - OH}\limits_{{\text{Vinyl}}\,{\text{alcohol}}} \xrightarrow{{KMn{O_4}}}$
(a) $\mathop {CH \equiv CH}\limits_{{\text{Ethyne}}} + {H_2}O\mathop {\xrightarrow{{HgS{O_4}}}}\limits_{{H_2}S{O_4}} \mathop {C{H_2} = CH - OH}\limits_{{\text{Vinyl}}\,{\text{alcohol}}} \xrightarrow{{KMn{O_4}}}$
