Hello students, hope you are doing great.

In this question, we are asked to prepare the rignard's reagent using 2 -bromobutane.
00:09
So, in the first case, here we have 2 -bromobutane which reacts with magnesium metal in presence of ether and it forms a rignard's reagent like this.
00:20
So, here we have mgbr.
00:23
We know that metal has the tendency of having a positive charge, so magnesium has positive charge and this carbon has a negative charge.
00:30
In the next step, the rignard's reagent formed in the first step reacts with 4 -methoxybenzaldehyde.
00:37
So, here we have benzene ring, we have aldehyde group present over first carbon and the methoxy group present on the fourth carbon...
