- A$HgS{O_4} + {H_2}S{O_4}$
- B$C{u_2}C{l_2}$
- ✓$C{u_2}C{l_2} + N{H_4}Cl$
- D$C{u_2}C{l_2} + N{H_4}OH$
✓
Answer
Correct option: C.
$C{u_2}C{l_2} + N{H_4}Cl$
c
Acetylene dimerized to give vinyl acetylene when it combines with hydrogen chloride to form $4$-chloro-$1, 2$-butadiene, an allene derivative, which in presence of cuprous chloride $\left( Cu _2 Cl _2\right)$ and ammonium chloride $\left( NH _4 Cl \right)$, rearranges to form $2$- Chlorobuta-$1, 3$-diene.
