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
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
I applied via Recruitment Consulltant and was interviewed in Jun 2022. There were 3 interview rounds.

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 ...
I applied via Walk-in and was interviewed in Jul 2022. There was 1 interview round.
The Dieckmann condensation or Dieckmann cyclization is a chemical reaction used to form a cyclic molecule from a diester.
The reaction involves the formation of a cyclic molecule from a diester through intramolecular nucleophilic substitution.
It is named after German chemist Walter Dieckmann.
The reaction is commonly used in the synthesis of cyclic ketones and lactones.
The reaction can be catalyzed by both acids and base...
Buchwald coupling is a palladium-catalyzed cross-coupling reaction used to form carbon-carbon bonds.
Buchwald coupling is a type of cross-coupling reaction in organic chemistry.
It involves the use of a palladium catalyst to form carbon-carbon bonds.
The reaction typically involves an aryl halide or pseudohalide and an organoboron compound as reactants.
Buchwald coupling is widely used in the synthesis of pharmaceuticals, ...

I applied via Walk-in and was interviewed in Aug 2022. There were 2 interview rounds.
Various types of catalysts can be used for coupling reactions, including transition metal catalysts, organometallic catalysts, and biocatalysts.
Transition metal catalysts, such as palladium, nickel, and copper catalysts, are commonly used for coupling reactions.
Organometallic catalysts, such as Grubbs catalysts or Schrock catalysts, can also be employed in certain coupling reactions.
Biocatalysts, such as enzymes, can c...
I applied via Referral and was interviewed in Nov 2022. There were 2 interview rounds.
Grignard reagent is an organometallic compound used in organic synthesis to form carbon-carbon bonds.
Grignard reagents are formed by reacting an alkyl or aryl halide with magnesium metal.
They are highly reactive and can be used to introduce a carbon chain into a molecule.
Grignard reagents are commonly used in the synthesis of alcohols, carboxylic acids, and ketones.
They can also be used for nucleophilic addition reacti...

Mechanism of reactions refers to the step-by-step process by which a chemical reaction occurs.
Mechanism of reactions involves the breaking and forming of chemical bonds.
It includes the identification of intermediates and transition states.
Understanding the mechanism of a reaction can help predict the outcome of the reaction and optimize reaction conditions.
Examples include SN1 and SN2 reactions in organic chemistry and
A 50 ppm solution contains 50 parts of solute per million parts of solution.
ppm stands for parts per million.
It is a measure of concentration.
In a 50 ppm solution, there are 50 parts of solute per million parts of solution.
For example, if we have a 1 million mL solution, there would be 50 mL of solute in it.
