Homework Answers
1,2 product is kineticalyy stable product so first one double is brominated due to persence of one mole of bromine. Hence option d is the right answer.
E is tha aromatic compound. Because it follow the huckel rule and one part of molecule se aromatic .
None of the atom se non aromatic.
Hence 0 is the right answer. Because some one is aromatic remaining is antiaromatic .
Thank you have a nice day
