Chemistry

o   Let the number of atoms of element A be N.

o   Tetrahedral voids = 2N.

o   Atoms of element M = (2/3) * 2N = 4/3 N.

o   The ratio M : A is (4/3 N) : N, which simplifies to 4:3.

o   So, the formula of the compound is M? A?

The Kjeldahl method is not applicable for nitrogen estimation in:

Compounds containing nitrogen in a nitro group.

Compounds containing an Azo group.

Pyridine.

Sucralose: Artificial sweetener

Glyceryl ester of stearic acid: The document incorrectly identifies this as "Sodium stearate which is synthetic detergent". Sodium stearate is a soap, not a synthetic detergent.

Sodium benzoate: Food preservative

Bithionol: Antiseptic

Linear: N? (azide ion)

Bent-shape: O? (ozone), NO? (nitrite ion), Cl? O (dichlorine monoxide)

1° amine: Forms a precipitate that is soluble in NaOH.

2° amine: Forms a precipitate that is insoluble in NaOH.

3° amine: No reaction.

Please consider the following Image

Inversion of Sucrose:
C? H? O? (Sucrose) + H? O - (Invertase)-> C? H? O? (Glucose) + C? H? O? (Fructose)

Fermentation of Glucose:
C? H? O? (Glucose) - (Zymase)-> 2C? H? OH (Ethanol) + 2CO?

KMnO? oxidizes alkanes that contain a tertiary hydrogen (3°H) to form tertiary alcohols.

n-alkanes, which do not contain tertiary hydrogens, are not oxidized by KMnO? under these conditions.
