Question

Give the major organic product(s) of the following reactions or sequences of reactions. Show the stereochemistry and/or isotope position clearly where it is relevant. If you think that the reaction would not occur, write as "NR" or "No Reaction."

A) ON CI 'N AlCl3 B) Br-N hu, CC14 ? Br2, FeBrz

Answer 1

All these are aromatic electrophilic substitution Reactions.

Electrophile addition occurs in these Reaction.

Electrophile is electron deficient species, so it adds on the site having higher electron density.

+R effecting groups increases electron density on ortho/para position, so electrophile adds on these positions while in -R group compounds, it adds on Meta position.

* NBS does allylic/ benzylic bromination due to more stable free radical.
