What is the main product when 1-bromopropane reacts with magnesium in dry ether?

Step 1: Identify the starting material, which is 1-bromopropane. This is a compound that contains a bromine atom attached to a three-carbon chain (propane).
Step 2: Understand that magnesium is a metal that can react with organic halides like 1-bromopropane.
Step 3: Recognize that the reaction takes place in dry ether, which is a solvent that helps the reaction occur without water.
Step 4: When 1-bromopropane reacts with magnesium, the bromine atom is replaced by a magnesium atom, forming a new compound.
Step 5: The product formed is called propylmagnesium bromide, which is a type of Grignard reagent used in organic chemistry.
