Intonation Research Laboratories Interview Questions and Answers

One way to extract acid product from reaction mixture without using a column is through liquid-liquid extraction.

• Perform liquid-liquid extraction using a solvent that selectively extracts the acid product

• Separate the layers and collect the solvent layer containing the acid product

• Repeat the extraction process if necessary to increase yield

• Evaporate the solvent to obtain the pure acid product

Cis and trans structures can be differentiated analytically based on their molecular symmetry and spectroscopic properties.

• Cis isomer has similar groups on the same side of the double bond, while trans isomer has them on opposite sides.

• Analytical techniques like NMR spectroscopy can be used to determine the spatial arrangement of atoms in a molecule.

• Infrared spectroscopy can also be helpful in distinguishing between ci...read more

Chlorine molecule in mass spectroscopy shows a 2:3 splitting pattern due to the presence of two isotopes, Cl-35 and Cl-37.

• Chlorine molecule (Cl2) contains two isotopes, Cl-35 and Cl-37.

• In mass spectroscopy, the chlorine molecule exhibits a 2:3 splitting pattern due to the isotopic distribution.

• The peak corresponding to Cl-35 is approximately 3 times higher than the peak corresponding to Cl-37.

• The relative intensities o...read more
