Answer:
Nitrobenzene is too deactivated (by the nitro group) to undergo a Friedel-Crafts alkylation.
Explanation:
The benzene ring in itself does not easily undergo electrophilic substitution reaction. Some groups activate or deactivate the benzene ring towards electrophilic substitution reactions.
-NO2 ia a highly deactivating substituent therefore, Friedel-Crafts alkylation of nitrobenzene does not take place under any conditions.
This reaction scheme is therefore flawed because Nitrobenzene is too deactivated (by the nitro group) to undergo a Friedel-Crafts alkylation.
<h2>Answer with Explanation </h2>
The energy transformation involved in heating soup in microwaves occurs due to microwave radiation. The radiant energy which also known as heat energy in the microwave causes the water molecules in the soup to gain kinetic energy. Hence, the molecules collide with each other more often causing the soup to heat up in form of waves that are built within the microwave. This is also the reason it is termed as mircowave due to release of waves.
Mass of Iron (Fe): 55.845Mass of Bromine (Br): 79.904
You need to multiply the mass of Br by 3 because there are 3 Bromine atoms.
(79.904)(3)+ 55.845= 239.712+55.845 = 295.557 g/mol
