Ncert Solutions Chemistry Class 12th

At the point of intersection in an Ellingham diagram? G for two processes becomes equal, so? G for the reduction becomes zero. A sudden increase in the slope indicates a change in the state of the metal oxide, i.e., from solid to liquid or liquid to vapor.

In the ammonolysis process, bond cleavage is carried out in the presence of NH? When a halide compound is treated with NH? , the halide ion (X? ) is substituted by an amino group (NH? ) in a nucleophilic substitution reaction.

A more reactive carbonyl, i.e., a ketone, is masked with ethylene glycol first in an acidic medium.

Allosteric inhibitors are a type of drug-enzyme inhibitor that binds to a site other than the active site of the enzyme, causing a conformational change that affects the active site. The statement in the document incorrectly states they bind at the active site due to steric factors.

A divalent metal ion with an atomic number (Z) of 25 is Mn²?
Mn²? (Z=25) has the electronic configuration: 3d? 4s? (n=5, five unpaired electrons).
The magnetic moment (μ) is calculated as: μ = √ [n (n+2)] = √ [5 (5+2)] = √35 = 5.92 BM.

Solid sol is a colloidal system consisting of a gas dispersed in a solid, e.g., pumice stone, foam rubber.

This describes a nucleophilic aromatic substitution reaction. Aryl halides are very less reactive toward this reaction, so the reaction takes place at a high temperature, i.e., 623K, and high pressure of 300 atm.

Ellingham diagram provides information on Gibb's free energy for formation of oxides as a function of temperature.
