SK Biobiz R&D Trainee Interview Questions, Process, and Tips

A weak acid is an acid that only partially dissociates in water, resulting in a lower concentration of hydrogen ions.

• Weak acids have a pH value greater than 3.5

• They have a lower degree of ionization compared to strong acids

• Examples of weak acids include acetic acid (vinegar), citric acid (lemons), and carbonic acid (soda)

A strong acid is a chemical compound that completely dissociates in water to produce hydrogen ions.

• Strong acids have a pH less than 3

• They are highly reactive and corrosive

• Examples include hydrochloric acid, sulfuric acid, and nitric acid

The Beckmann reaction is a chemical reaction that involves the conversion of an oxime into an amide.

• The reaction is typically carried out using acid catalysts, such as sulfuric acid or hydrochloric acid.

• The reaction proceeds through a rearrangement of the oxime to form an isocyanate intermediate, which then reacts with water to form the amide.

• The Beckmann reaction is commonly used in the synthesis of pharmaceuticals an...read more

Pinacol-pinacolon reaction is a type of organic reaction that involves the conversion of a pinacol to a pinacolone.

• In this reaction, a carbon-carbon bond is broken and a new carbonyl group is formed.

• The reaction is catalyzed by an acid catalyst such as sulfuric acid or hydrochloric acid.

• The reaction mechanism involves the formation of a carbocation intermediate.

• The pinacol-pinacolon reaction is an important reaction in...read more

Oxidation reaction is a chemical reaction that involves the loss of electrons by a substance.

• It is a process in which a substance combines with oxygen or loses hydrogen.

• It results in an increase in the oxidation state of the substance.

• Examples include rusting of iron, combustion of fuels, and metabolism of food in the body.

• It is the opposite of reduction reaction.

• It is important in various fields such as chemistry, bio
