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.

Answer:
In plants, chloroplasts occur in all green tissues, though they are concentrated particularly in the parenchyma cells of the leaf mesophyl. An example of a chloroplast is a cell in algae that consumes carbon dioxide and releases oxygen while creating sugar. A plastid that contains chlorophyll and is found in the cells of green plants and algae.

<span>The periodic table of elements is ordered by atomic weight from the top left to the bottom right. Each column is assigned a group, they can be either A groups or B groups. To determine the lightest element in the 1A group, locate the 1A column, at look at the top most element. In this case, H, hydrogen.</span>
