Question

What is Frankland reagent?

Answer 1

1. In an organic reaction, a lot of compounds are used in the reaction which does not work as a reactant.
2. Such compounds are called reagents which encourage the reactants to form the products.
3. Edward Frankland synthesize the organic compound and named a reaction called “Frankland reaction” in which Frankland reagent is used.
4. Frankland reagent is an organometallic compound that contains two ethyl groups attached with a single Zinc atom.
5. The reagents are highly reactive because Zinc is electropositive and Ethyl is slightly negative, this creates the polarity on the compound which easily leaves the alkyl group in the reaction.
6. The reaction occurs between an alkyl halide$\left(C_2{H}_5-X\right)$ and Zinc metal$\left(\mathrm{Zn}\right)$ to form Dialkyl Zinc${\mathbf{\left(}{\mathbf{C}}_{\mathbf{2}}{\mathbf{H}}_{\mathbf{5}}\mathbf{\right)}}_{\mathbf{2}}\mathbf{Zn}$( Frankland Reagent).
7. The reaction is represented as follows:
   $\underset{(\mathrm{Ethyl}\mathrm{halide})}{2{\mathrm{C}}_2{\mathrm{H}}_5-\mathrm{X}\left(\mathrm{g}\right)}+\underset{(\mathrm{Zinc}\mathrm{metal})}{2\mathrm{Zn}\left(\mathrm{s}\right)}\to \underset{(\mathrm{Diethyl}\mathrm{Zinc})}{{\left({\mathrm{C}}_2{\mathrm{H}}_5\right)}_2\mathrm{Zn}\left(\mathrm{l}\right)}+{\mathrm{ZnX}}_2\left(\mathrm{l}\right)$
