Which is more acidic, 3-nitrophenol or 2-nitrophenol and why? Which is more basic, benzyl amine or aniline and why? Which is mor
Anika [276]

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

Use the following key to classify each of the elements below in its elemental form:
tiny-mole [99]

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.
