Question

Ethyl isocyanides is obtained by treating ethyl chloride with.
A) $NaCN$
B) $AgCN$
C) $KCN$
D) Both $AgCN$ and $KCN$

Answer 1

We all know that in the chemical reaction if one metal displaces to another compound form a new product called chemical displacement reaction.
Example: $Zn + 2HCl \to ZnC{l_2} + {H_2}$
In the given example reaction the chlorine present in HCl is replaced by hydrogen and that chlorine combines with zinc to form zinc chloride as a product.

Complete step by step answer:
Complete step by step answer:
We can write the chemical equation for the given reaction as,
${C_2}{H_5}Cl + AgCN \to {C_2}{H_5}CN + AgCl$
Ethyl chloride reacts with $KCN/NaCN$ and alkyl cyanide forms.
But ethyl chloride reacts with$AgCN$ and isocyanide forms because in $NaCN/KCN$, the bonds are ionic between metal and Cyanide, so carbon end is free to make bonds while $AgCN$ has a covalent bond among them so carbon end not free.
Thus isocyanide is formed with $AgCN$.

So, the correct answer is Option B.

Additional Note:
We have to remember that the neutralization and precipitation reactions are some more instances of double decomposition reactions.
Neutralization:
Neutralization might be a double decomposition that happens between the acids and bases. The reactions among vinegar and bicarbonate of pop is a case of balance.
Precipitation reactions:
Precipitation reactions might be a double decomposition that happens between two fluid ionic mixes which structure a substitution insoluble ionic compound. The reactions between lead (II) nitrate and iodide is a case of precipitation reactions.
Substance decay:
The substance reactions in which reactants deteriorates into at least two items called synthetic disintegration
Model: $CaC{O_3}\xrightarrow{\Delta }CaO + C{O_2}$

Note: Presently we see the double decomposition reactions.
The reactions where the two reactants trade their positive and negative particles and structure another compound is known as a double decomposition reaction and furthermore called uprooting reactions. The overall condition of the reactions is,
$AB + CD \to AD + CB$
Let us see a case of double decomposition reactions.
On warming, ferrous sulfate gems lose water and it structures anhydrous ferrous sulfate so the shade of the precious stone changes from light green to white, and on additional warming anhydrous ferrous sulfate disintegrates to give ferric oxide, sulfur dioxide, and sulfur trioxide.
$2FeS{O_4}\xrightarrow{\Delta }F{e_2}{O_3} + S{O_2} + S{O_3}$
In the single reactions ferrous sulfate disintegrated into three items subsequently it is a decay reaction.
