R&D Trainee Interview Questions and Answers for Freshers

Spectroscopy is the study of interaction between matter and electromagnetic radiation. It has various tools to analyze different properties of matter.

• Spectrophotometry measures the absorption and transmission of light by a substance

• Fluorescence spectroscopy measures the fluorescence emitted by a substance when excited by light

• Raman spectroscopy measures the scattered light from a substance to determine its vibrational modes

• X-ray spectroscopy measures the energy of X-rays abso...read more

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 and other organic compounds.

• For example, the reaction can be...read more

Cyclic voltammetry is an electrochemical technique used to study the redox properties of a molecule or material.

• Involves applying a potential to a sample and measuring the resulting current

• The potential is varied in a cyclic manner to obtain information about the redox properties

• Can be used to determine the oxidation state of a molecule or the electrochemical behavior of a material

• Commonly used in battery research and corrosion studies

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

Thermodynamics law is applied to study energy transfer and conversion in various systems.

• Thermodynamics law helps in understanding how energy flows in a system.

• It is used to analyze heat engines, refrigerators, and chemical reactions.

• The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.

• The second law of thermodynamics states that the entropy of an isolated system always increases over time.

• Thermodynamics is crucial i...read more
