Spc Life Sciences QC Chemist Interview Questions, Process, and Tips

Q1. Define Suzuki coupling reaction
Ans. 
Suzuki coupling reaction is a cross-coupling reaction between an organoboron compound and an organic halide catalyzed by a palladium catalyst.
• Involves the coupling of an organoboron compound with an organic halide

• Catalyzed by a palladium catalyst

• Forms a new carbon-carbon bond

• Widely used in organic synthesis

• Example: Coupling of phenylboronic acid with bromobenzene

Q2. NMR chemical shift values
Ans. 
NMR chemical shift values are unique for each type of atom in a molecule and are influenced by surrounding chemical environment.
• Chemical shift values are measured in parts per million (ppm) relative to a standard reference compound.

• Different types of atoms (e.g. hydrogen, carbon) have characteristic chemical shift ranges.

• Chemical shift values can be influenced by factors such as neighboring atoms, functional groups, an

Q1. Functional group, compound structure and name , it's molecular weight,
Ans. 
Functional group, compound structure, name, and molecular weight are key aspects of organic chemistry.
• Functional group: Determines the chemical properties of a compound.

• Compound structure: Shows how atoms are arranged in a molecule.

• Name: Identifies the compound based on its structure and functional groups.

• Molecular weight: Sum of the atomic weights of all atoms in a molecule.

Q2. Gc principle and analysis.
Ans. 
Gas chromatography (GC) is a technique used to separate and analyze compounds in a mixture based on their volatility.
• GC relies on the principle of separating compounds based on their partitioning between a stationary phase and a mobile phase.

• Compounds with higher volatility will travel through the column faster and be detected earlier.

• GC is commonly used in the analysis of organic compounds, such as in drug testing or ...read more

Ans. 
Spectroscopy techniques NMR and IR are commonly used in chemistry research and analysis.
• NMR (nuclear magnetic resonance) spectroscopy is used to determine the structure and composition of molecules by analyzing their magnetic properties.

• IR (infrared) spectroscopy is used to identify functional groups in molecules by analyzing their absorption of infrared radiation.

• Both techniques are non-destructive and can be used to ...read more
