Chemistry

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.

In an aqueous medium, all alkali metal cations are converted into their hydrated form. More intensely positive cations have more hydration, and hence the size of the cation increases after hydration. Therefore, the Li? cation has a larger size in hydrated form and the least conductivity. The order of conductivity of alkali metal ions is: Li? < Na? < K? < Rb? < Cs?

Except for option (D), all are the important characteristics of D? O. D? O is useful for the isotopic leveling effect in reaction mechanisms. The dielectric constants of H? O and D? O are respectively 80 and 60.

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