Question

What sorts of information can you draw from the following reactions : $(CN)_{2}(g)+2OH^{-}(aq)\longrightarrow CN^{-}(aq)+CNO^{-}(aq)+H_{2}O(l)$

Answer 1

The given reaction is as follows,

${ \left( CN\right)}_{ 2 }(g)\quad +\quad 2{ OH }^{ - }(aq)\quad \rightarrow \quad { CN }^{ - }(aq)\quad +\quad { CNO }^{ - }(aq)\quad +\quad { H }_{ 2 }O(l)$

Let's calculate the "oxidation states" of each reactants and product.

$\begin{matrix} { \left( CN \right)_{ 2 } \\ C\quad =\quad x \\ 2\left( x-3 \right) =0 \\ x\quad =\quad 3 \end{matrix}\begin{matrix} { CN }^{ - } \\ C\quad =\quad x \\ x-3\quad =\quad -1 \\ x\quad =\quad 2 \end{matrix}\begin{matrix} { CNO }^{ - } \\ C\quad =\quad x \\ x-3-2\quad =\quad -1 \\ x\quad =\quad 4 \end{matrix}$

The given reaction is decomposition of ${ \left( CN \right) }_{ 2 }$ in the presence of alkaline medium. It is an example of reduction reaction and also cyanogen undergoes disproportionation.

Answer 2
