Question

With what would a Grignard reagent react?

Answer 1

Any electrophile..........

Explanation:

And so, amongst other things, we could add `H_3O^+`, `"alkyl halides"`, `"silyl halides"`, `"acyl halides"`, even `"carboxylic acids"`.........

You should be able to predict the product and draw the mechanism of reaction in each case.
