Answer
1) among them only electron donating group is alkyl . All the rest are electron withdrawing
hence Ansina alkyl group
2) Answer is option b
please refer the reaction mechanism shown in paper
3) For a compound to be aromatic , it should have 4n +2 pi electron where n = 0,1,2,3,4,etc....
if the no of double bonds and lone pairs adds to obey the 4n + 2 rule , then it would be aromatic
in the given options , the option e has only one double bond and a lone pair electron which sum up to only 4 electron and it doesn't obey the 4n+2 rule
so the Amswer is option e
