Answer:
2-nitrophenol is more acidic than 3-nitrophenol
benyl amine is more basic than aniline
dimethylamine is more basic than triethylamine
Explanation
Mesomeric effect stabilizes the anion formed when hydrogen of the the -OH group in the 2-nitrophenol is lost. This mesomerism is most pronounced at the 2 and 4 position.
Stronger bases have more available lone pair of electrons. The lone pair of electrons in aniline is delocalized over the ring. Hence it is unavailable for protonation while the lone pair on benzyl amine is available for protonation
Diethylamine is a stronger base because it has a balance of both inductive electron donation by alkyl groups, and solvation of the conjugate acid unlike triethylamine. Hence Diethylamine is a stronger base than triethylamine
Answer:
Magnesium - Metallic lattice
Nitrogen - Molecules
Lithium - Metallic lattice
Potassium - Metallic lattice
Explanation:
Metals exist in metallic lattices. In this lattice, metal ions are held together with a sea of electrons by strong electrostatic forces.
All metals possess this metallic lattice, hence; potassium, lithium and magnesium all consist of metal lattices.
Nitrogen is a nonmetal and consists of molecules of N2.
It is the same as a proton. That is why, if hydrogen was a molecule not an ion, one electron is needed to 'cancel' out the proton.
Saturated.
An unsaturated solution is a solution where more solute can still be added.
