Junior Research Associate Interview Questions and Answers for Freshers

MCPBA is a powerful oxidizing agent used in organic chemistry reactions.

• MCPBA stands for meta-chloroperoxybenzoic acid.

• It is commonly used to convert alkenes into epoxides.

• The mechanism involves the transfer of an oxygen atom from MCPBA to the double bond of the alkene, forming an epoxide.

• MCPBA can also oxidize sulfides to sulfoxides and sulfones.

• It is a versatile reagent in various oxidation reactions.

Beckmann rearrangement is a chemical reaction that involves the conversion of an oxime to an amide.

• The reaction is carried out in the presence of a strong acid catalyst, such as sulfuric acid or hydrochloric acid.

• The oxime is first protonated by the acid catalyst, which then undergoes rearrangement to form an isocyanate intermediate.

• The isocyanate intermediate then reacts with water to form the desired amide product.

• The reaction is widely used in the synthesis of various amid...read more

Revenue drivers are factors that contribute to the growth of a company's revenue.

• Revenue drivers can be internal or external factors

• Examples of internal revenue drivers include product innovation, pricing strategy, and marketing efforts

• Examples of external revenue drivers include changes in market demand, economic conditions, and competition

• Identifying and focusing on revenue drivers can help a company increase its revenue and profitability

Suzuki coupling is a palladium-catalyzed cross-coupling reaction between organoboron compounds and organic halides.

• The reaction involves the oxidative addition of the organic halide to the palladium catalyst, followed by transmetalation with the organoboron compound.

• The resulting intermediate undergoes reductive elimination to form the coupled product.

• Suzuki coupling is widely used in organic synthesis to form carbon-carbon bonds.

• For example, it can be used to synthesize biar...read more
