(a)
Interpretation:
The percent transmittance of a solution needs to be defined.
Concept Introduction :
The percentage of light that gets absorbed when it is passing through solution is termed as transmittance. This light which passes through gets detected by the instrument.
(b)
Interpretation:
The neat solution needs to be explained.
Concept Introduction :
A
(c)
Interpretation:
The termhygroscopic needs to be explained.
Concept Introduction :
The phenomenon where the water molecules are attracted and held together via absorption or adsorption from its surrounding environment at room temperature is said to be hygroscopy.
(d)
Interpretation:
Thefixed thickness cell needs to be explained.
Concept Introduction :
There are specific methods for measurements for liquid samples of infra-red spectroscopy. For transmission methods, there are various types of cells used like liquid cell, fixed cell etc.
(e)
Interpretation:
Thefunctional group needs to be explained.
Concept Introduction :
There are specific substitutes or bonded molecules within the compound that is responsible for chemical reactions which are characteristic to it. These molecules or groups are called as
(f)
Interpretation:
Thestretching vibrational mode needs to be explained.
Concept Introduction :
As per Heisenberg’s Uncertainty principle, all atoms in molecules are constantly in motion. The motion is commonly identified as translational, vibrational, and rotational.
(g)
Interpretation:
The bending vibrational mode needs to be explained.
Concept Introduction :
Heisenberg’s Uncertainty principle states that all atoms in molecules are constantly in motion. The motion of the atomsis commonly identified as translational, vibrational, and rotational.
(h)
Interpretation:
Thesuperimposibility (as applied in IR spectroscopy) needs to be explained.
Concept Introduction :
No two compounds can have the exact same IR spectrum. Also, IR spectrum is said to be the fingerprint of the compound. Most of the compounds have their unique fingerprints in the range of 1500cm-1.

- Use the References to access important values if needed for this question. What is the IUPAC name of each of the the following? 0 CH3CHCNH₂ CH3 CH3CHCNHCH2CH3 CH3arrow_forwardYou have now performed a liquid-liquid extraction protocol in Experiment 4. In doing so, you manipulated and exploited the acid-base chemistry of one or more of the compounds in your mixture to facilitate their separation into different phases. The key to understanding how liquid- liquid extractions work is by knowing which layer a compound is in, and in what protonation state. The following liquid-liquid extraction is different from the one you performed in Experiment 4, but it uses the same type of logic. Your task is to show how to separate apart Compound A and Compound B. . Complete the following flowchart of a liquid-liquid extraction. Handwritten work is encouraged. • Draw by hand (neatly) only the appropriate organic compound(s) in the boxes. . Specify the reagent(s)/chemicals (name is fine) and concentration as required in Boxes 4 and 5. • Box 7a requires the solvent (name is fine). • Box 7b requires one inorganic compound. • You can neatly complete this assignment by hand and…arrow_forwardb) Elucidate compound D w) mt at 170 nd shows c-1 stretch at 550cm;' The compound has the ff electronic transitions: 0%o* and no a* 1H NMR Spectrum (CDCl3, 400 MHz) 3.5 3.0 2.5 2.0 1.5 1.0 0.5 ppm 13C{H} NMR Spectrum (CDCl3, 100 MHz) Solvent 80 70 60 50 40 30 20 10 0 ppm ppm ¹H-13C me-HSQC Spectrum ppm (CDCl3, 400 MHz) 5 ¹H-¹H COSY Spectrum (CDCl3, 400 MHz) 0.5 10 3.5 3.0 2.5 2.0 1.5 1.0 10 15 20 20 25 30 30 -35 -1.0 1.5 -2.0 -2.5 3.0 -3.5 0.5 ppm 3.5 3.0 2.5 2.0 1.5 1.0 0.5 ppmarrow_forward
