Answer 1

A Grignard reagent may be made by reacting magnesium with ethyl iodide (${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{I}$)

Chemical reaction: $\underset{\mathrm{Ethyl}\mathrm{iodide}}{{\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{I}}+\underset{\mathrm{Magnesium}}{\mathrm{Mg}}\stackrel{\mathrm{Dry}\mathrm{ether}}{\to }\underset{\mathrm{Ethyl}\mathrm{magnesium}\mathrm{bromide}}{{\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{Mg}-\mathrm{I}}$
