Homework Answers
1. Options A,B and D are aromatic since they are planar and follow Huckle rule of 4n+2 pi electron rule
B. Anthracene is an aromatic hydrocarbon and exists in the following resonance structures.
3. It is an example for Aromatic Electrophilic substitution and Electrophilic species is Br+
Since ketone is meta directing group hence substituion occurs at meta direction.

When naphthalene undergoes an irreversible electrophilic aromatic substitution, the major product is the kinetic product, which proceeds through the most stable arenium ion intermediate. With this in mind, draw the curved arrow mechanism for the first step of the electrophilic aromatic substitution of naphthalene with l^+ generated from l_2 and CuCl_2. If you predicted the correct regiochemistry in the first step, then you can draw the curved arrows and a resonance structure in step 2 with an unbroken benzenoid ring....
