What would be the product of 1-bromopropane with Mg in diethyl ether??
The product is called Grignard reagent and the formula is
Grignard reagents are very useful precursors in synthetic organic chemistry, since they are easy to prepare and they react relatively fast.
One thing to keep in mind is that once a Grignard reagent is prepared, it should be kept way of moisture. Therefor, the diethyl ether should be anhydrous.
