A) \[C{{H}_{2}}\]
B) \[{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{4}}}\]
C) \[{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{3}}}\]
D) \[{{\text{C}}_{6}}{{\text{H}}_{8}}\]
Correct Answer: A
Solution :
\[~\text{Xe}\] \[\text{C}{{\text{u}}^{2+}}\text{+4C}{{\text{N}}^{-}}\xrightarrow{{}}{{\text{ }\!\![\!\!\text{ Cu(CN}{{\text{)}}_{4}}\text{ }\!\!]\!\!\text{ }}^{3-}}\text{more stable}\] \[\text{C}{{\text{d}}^{\text{2}+}}\text{+ 4C}{{\text{N}}^{-}}\xrightarrow{{}}{{\left[ \text{Cd}{{\left( \text{CN} \right)}_{\text{4}}} \right]}^{\text{3}-}}\text{less stable}\] \[\text{C}{{\text{d}}^{+}}\] \[\text{C}{{\text{u}}^{\text{2}+}}\] \[\text{C}{{\text{u}}^{\text{2}+}}\] \[\text{C}{{\text{N}}^{-}}\] \[{{[Ar]}^{18}}3{{d}^{3}}4{{s}^{2}}\] \[\text{4}{{\text{s}}^{\text{2}}}\]You need to login to perform this action.
