Friedel-Crafts Acylation of Ferrocene "riedel-Crafts reactions are examples of electrophilic aromatic substitution reactions. The eaction involves the substitution of hydrogen on the aromatic ring system by an electrophilic arbon species forming a new carbon-carbon bond. Friedel-Crafts reactions may be used to ntroduce either an alkyl or acyl group. Ferrocene does not undergo addition reactions typical of cyclopentadiene, but undergoes Electrophilic aromatic substitution. The Friedel-Crafts acylation reaction of ferrocene involves he addition of the acylium cation to one of the carbon...

In Tolkein's "The Lord of The RIngs" Legolas the elf can accurately count horsemen and discern their hair color from a distance of 5 leagues on a bright, sunny day. Assume one leage is 5km, and that you can distinguish hair color if you resolve the head of a horseman, which has a typical size of 20cm. You may neglect curvature of the earth. a). Assuming elves have eyes that are optimized for optical light as we see (peak wavelength=5500Å),...
