Hi, in this question we are asked to choose the substance that activates the benzene ring towards electrophilic aromatic substitution reaction.
00:09
Here we can say that electrophilic aromatic substitution is a chemical reaction in which hydrogen attached benzene ring or any compound is replaced by an electrophile.
00:42
We know that electrophile is electron deficient species or we can say electron loving species.
00:51
Therefore, for this we can say the benzene ring which is drawn in this manner should be electron rich and those substituents which abstract the electron density from the benzene ring are not favorable for electrophilic aromatic substitution whereas those which provide electron density to the benzene ring are the activating groups.
01:19
Hence, let us check the given options.
01:22
In the first option we have so3h.
01:26
This group is electron withdrawing group due to presence of highly electronegative oxygen atom in this.
01:35
Hence, this deactivates the benzene ring.
01:43
In the second option we have nh2 group...
