Interpretation:
The spectroscopic structure identification for given statement of molecular formula should be draw and identified.
Concept Introduction:
NMR Spectroscopy: NMR spectroscopy commonly known as MRI (Magnetic Resonance Spectroscopy), it is important Research tool of analysis for different organic molecule and its structures.
1H NMR Spectroscopy: The 1H NMR (or) single hydrogen (H) is the application of NMR spectra with respect to hydrogen nuclei within the molecules of a substance, in order to determine the structure of its molecules.
Chemical Shift: The chemical shift in absolute terms is defined by the frequency of the resonance expressed with reference to a standard compound which is defined to be at 0 ppm. The scale is made more manageable by expressing it in parts per million (ppm) and is independent of the spectrometer frequency. For example, a peak at a chemical shift, δ, of 10 ppm is said to be downfield or deshielded with respect to a peak at 5 ppm
To find: The molecular formula for the given statement of molecules (a)

- Phenol is the starting material for the synthesis of 2,3,4,5,6-pentachlorophenol, known al-ternatively as pentachlorophenol, or more simply as penta. At one time, penta was widely used as a wood preservative for decks, siding, and outdoor wood furniture. Draw the structural formula for pentachlorophenol and describe its synthesis from phenol.arrow_forward12 Mass Spectrometry (d) This unknown contains oxygen, but it does not show any significant infrared absorption peaks above 3000 cm . 59 100- BO 40 Relative Abundance M(102) - 15 20 25 30 35 40 45 50 5 60 65 70 75 80 85 90 95 100 105 mizarrow_forwardDraw a Haworth projection of a common cyclic form of this monosaccharide: H HO H HO H HO H H -OH CH2OH Click and drag to start drawing a structure.
