A) \[{{C}_{2}}{{H}_{6}}\]
B) \[{{C}_{2}}{{H}_{4}}\]
C) \[{{C}_{2}}{{H}_{2}}\]
D) \[{{C}_{6}}{{H}_{6}}\]
Correct Answer: C
Solution :
\[2N{{H}_{4}}OH+C{{u}_{2}}C{{l}_{2}}\to 2CuOH+2N{{H}_{4}}Cl\] \[N{{H}_{4}}OH+CuOH\to \underset{\begin{smallmatrix} \text{Diammine copper} \\ \text{ }\left( I \right)\text{ hydroxide} \end{smallmatrix}}{\mathop{[Cu{{(N{{H}_{3}})}_{2}}]OH}}\,\] \[2[Cu{{(N{{H}_{3}})}_{2}}]\,OH+HC\equiv CH\to \] \[\underset{\text{copper acetylide Red ppt}\text{.}}{\mathop{Cu-C\equiv C-Cu}}\,+4N{{H}_{3}}+2{{H}_{2}}O\]You need to login to perform this action.
