Question

Why is a Grignard reagent very reactive?

Answer 1

A Grignard reagent is written as `"R"-"MgX"`, and `"X"` is often `"Br"`.

`"R"` here is negatively charged, i.e `"R"` is the alkyl or aryl group; when the terminal carbon bears the negative charge, it becomes an exceptional nucleophile against a positively-charged or electron deficient centre.

Note - Grignard reagent reaction is always carried out in dry ether solvent to get specified product to prevent deactivation of the nucleophile.
