Answer:
Samira's model is incorrect because not all atoms are accounted for
Explanation:
The image of Samira's model has been attached to this answer to enhance the explanation.
What is depicted in that model is rightly regarded as a chemical change. In a chemical change atoms of substances are rearranged as new substances are formed.
However, all atoms in the products must also be found in at least one of the reactants. In this case we have an atom in one of the products that is not accounted for. Hence the model is incorrect.
C – coming to
senses and finally realized that everything is dynamic and I should learn to
invest into knowing what of these changes are right or wrong and being
H – hopeful that
someday, these changes will actually make sense and that all of these questions
and confusions will be answered in the right time and the right place. But
whatever happens, I must learn to
A – adapt from
the different things I see everyday, If the world changes for its betterment or
for its worse, then I too, should change as well to go with the flow. However,
keep in mind to
N – never leave
the small things behind because these things when summed up actually what make
sense of everything and could possibly answer the
G – growing dynamics
of the world and its inhabitants. Throughout all this, it is always important
to
<span>
E-educate
yourself, that when the change will finally take effect on you, you will be
ready.</span>

Answer:
The order of reactivity towards electrophilic susbtitution is shown below:
a. anisole > ethylbenzene>benzene>chlorobenzene>nitrobenzene
b. p-cresol>p-xylene>toluene>benzene
c.Phenol>propylbenzene>benzene>benzoic acid
d.p-chloromethylbenzene>p-methylnitrobenzene> 2-chloro-1-methyl-4-nitrobenzene> 1-methyl-2,4-dinitrobenzene
Explanation:
Electron donating groups favor the electrophilic substitution reactions at ortho and para positions of the benzene ring.
For example: -OH, -OCH3, -NH2, Alkyl groups favor electrophilic aromatic substitution in benzene.
The -I (negative inductive effect) groups, electron-withdrawing groups deactivate the benzene ring towards electrophilic aromatic substitution.
Examples: -NO2, -SO3H, halide groups, Carboxylic acid groups, carbonyl gropus.
