MCQ
A mixture of methane, ethylene and acetylene gases is passed through a Wolf's bottle containing ammoniacal cuprous chloride. The gas coming out is
- AMethane
- BAcetylene
- ✓A mixture of methane and ethylene
- DThe original mixture
$CH \equiv CH + 2\,[Cu{(N{H_3})_2}]OH \to $
$Cu - C \equiv C - Cu + 4N{H_3} + 2{H_2}O$
$C{H_4} + \,{\rm{Ammonical}}\,\,C{u_2}C{l_2} \to {\rm{No}}\,\,{\rm{reaction}}$
${C_2}{H_4} + \,{\rm{Ammonical}}\,\,C{u_2}C{l_2} \to {\rm{No}}\,\,{\rm{reaction}}$
