meta bromo chlorobenzene when reacted with one mole of Mg in dry ether
Answer
meta-chlorophenylmagnesium bromide
Explanation
Solution
Magnesium reacts with organohalides in dry ether to form Grignard reagents. Bromine is more reactive than chlorine in this reaction. Therefore, magnesium selectively inserts into the C-Br bond of meta-bromo chlorobenzene, forming meta-chlorophenylmagnesium bromide. The C-Cl bond remains unreacted under these conditions.
