(4 Questions)
- Q1. What type of chemistry you have done recently and what troubleshooting done in current year?
- Q2. Write down reaction mechanism of reaction?
- Ans.
The question asks for the reaction mechanism of a specific reaction.
Reaction mechanism refers to the step-by-step process of how a reaction occurs.
It involves the breaking and forming of chemical bonds.
The mechanism can be determined through experimental data and theoretical calculations.
Examples include SN1 and SN2 reactions in organic chemistry.
The mechanism can also be influenced by factors such as temperature, conc
- Q3. What would be the final product if we change this reagent with that one?
- Ans.
The final product would depend on the specific reagents used and the reaction conditions.
The final product could be different in terms of yield, purity, and chemical properties.
The reaction mechanism and kinetics could also be affected by the change in reagent.
Examples of changes in reagents could include using a different catalyst or solvent.
The final product could also be affected by the stoichiometry of the reaction...
- Q4. What is the role of particular reagent in reaction?
- Ans.
The role of a particular reagent in a reaction is to initiate, catalyze, or participate in the reaction.
Reagents can be used to initiate a reaction by providing energy or a catalyst to start the reaction.
Reagents can also be used to catalyze a reaction by lowering the activation energy required for the reaction to occur.
Reagents can participate in a reaction by reacting with other molecules to form new products.

- Q1. Explain chromatography
- Ans.
Chromatography is a technique used to separate and analyze mixtures of substances based on their different properties.
Chromatography involves a stationary phase and a mobile phase.
The stationary phase is a solid or liquid that the mixture is passed through.
The mobile phase is a liquid or gas that carries the mixture through the stationary phase.
Different components of the mixture interact differently with the stationar...

(2 Questions)
- Q1. Basic organic conversions
- Q2. NMR values of conversions
- Ans.
NMR values can be used to track the progress of chemical reactions and determine conversion rates.
NMR values can be used to monitor the disappearance of starting materials and appearance of products in a reaction.
The integration of NMR peaks can provide quantitative information about the extent of conversion.
Changes in chemical shifts or coupling patterns can also indicate progress of a reaction.
For example, in a react...

- Q1. What reagent used for acid -amine coupling?
- Ans.
The reagent used for acid-amine coupling is typically carbodiimides.
Carbodiimides are commonly used reagents for acid-amine coupling reactions.
Examples of carbodiimides include EDC (1-ethyl-3-(3-dimethylaminopropyl)carbodiimide) and DIC (diisopropylcarbodiimide).
- Q2. How to quench pyrophoric reagent?
- Ans.
Pyrophoric reagents can be quenched by using appropriate quenching agents.
Use a non-reactive quenching agent such as water, alcohol, or mineral oil.
Add the quenching agent slowly to the pyrophoric reagent while stirring gently.
Dispose of the quenched mixture according to safety guidelines.
Always wear appropriate personal protective equipment when handling pyrophoric reagents.
