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.
Answer:
2M
Explanation:
M=mol/L
1. Find moles of CoCl2
mass of substance/molar mass = 130/129.833 = 1.001 mol
3. Substitute in molarity equation
M=(1.001/0.5)
M= around 2M
The central vacuole stores materials, wastes, and helps give the plant structure and support.
Hope this helps!
Answer:
D. Positively charged particles
Explanation:
Negatively charged particles are attracted to positively charged particles and repelled against negatively charged particles
Answer:
its called TAXON0MY
Explanation:
they are classified in eight steps namely doma!n, k!ngdom, phylum, class, order, family, genus, and spec!es
but sometimes we do not include doma!n
if you want to name an organism you use both the genus group and the spec!es group
Example:
The scientific name for humans like us is h0m0 sap!ens
H0m0- This is our genus group
sap!ens- This is our spec!es group
sorry for using the exclamation mark it means i
