What starting compound and what reagents should be used for most efficient synthesis of 2-bromo-1-iso-propyl-4-nitrobenzene? Eff
icient synthesis means that on each step you take the major product or one of the major products and continue reacting it with assigned reagent further. The final product is must be major product of the reaction as well. Select one:
A. Start with iso-propylbenzene First step: HNO,+H2S04 Second step: Br2+FeBr
B. Start with bromobenzene First step: HNO,+H2SO Second step: 2-chloropropane + AIC
C. Start with nitrobenzene First step: 2-chloropropane +AICI Second step: Br,+FeBr
Alkyl substituents on benzene are ortho, para directing. They activate the benzene ring towards electrophilic substitution at the 2 and 4 positions. Nitration is an electrophilic addition to the benzene ring and will occur at the 2 and 4 positions. The para nitro product predominates due to steric effects. Bromine, being smaller than -NO2 can be directed to the ortho position. Hence te compound is formed
Chlorine gas is a poisonous and very toxic gas. Chlorine is a moderately reactive halogen. It is a greenish-yellow gas with choking and irritating smell. The gas is very poisonous. Proper care must be taken when working with this gas.
This is why chlorine gas are harmful in production of fireworks.
They are more likely to be covalent as covalent compounds usually tend to be radical on the color spectrum with deep purples and blacks and even earwax colored.
