Looking at the IR spectra how can you tell this is an alkene? **Transcription and Analysis for Educational Purposes: Infrared (IR) Spectroscopy Graph****Graph Components:**- **Title:** IR- **Y-Axis:** Transmittance (%)- **X-Axis:** Wavenumber (cm⁻¹), ranging from 4000 to 500 cm⁻¹.**Description of Graph:**This graph is an infrared (IR) spectroscopy spectrum that displays the transmittance of a sample as a function of wavenumber. The graph represents how much infrared light passes through a sample versus being absorbed at different wavenumbers, which correlates with different molecular vibrations.**Key Features:**1. **Transmittance Levels:** - The transmittance is shown as a percentage, ranging from 0% to 100%. - High peaks represent higher transmittance (less absorbance), while troughs indicate regions of low transmittance (high absorbance).2. **Wavenumber Range:** - The x-axis covers the full range from 4000 cm⁻¹ to 500 cm⁻¹, which includes most of the common functional group frequencies. - Notable absorptions occur at different wavenumbers indicative of specific molecular vibrations.3. **Interpretation of Peaks:** - Each sharp drop or trough on the graph signifies an absorption peak, which corresponds to the vibrations caused by specific bonds in the sample. - These peaks can be used to identify different functional groups present within the sample.4. **Usage:** - This type of IR spectrum can be used to determine the functional groups present in the analyzed compound, assisting in molecular identification and characterization. In essence, this graph is a tool for molecular characterization allowing chemists to infer the presence of certain bonds and functional groups based on their unique infrared absorption patterns.

(Please show all of your work so I can understand how to solve this problem, also you will need to use a special periodic table which is attached in the images) For this problem, draw all hydrogen atoms explicitly. Draw the structure of the following: a) 2,4-diboguso-1-propylbenzene (boguso is Bg on the special periodic table) b) cis-1,2-dibogusoethene (boguso is Bg on the special periodic table)
Among a primary, secondary, or tertiary carbocation, which is most favored for SN1 reactions? Explain why
Draw out the mechanism to explain this reaction - pls include formal charges, lone pairs, arrows and a transition state - use dashes and wedges - lastly what is the stereochemistry of this rxn? why doesn’t it apply to this situation?
C. Draw the structure of the synthesized product (do not include side or by products) from the experiments performed. How can IR spectroscopy be used to monitor the progress of each of the following reactions (if reaction went to completion and/or check the purity of the final product)? What absorptions would be observed in the IR spectrum? And if IR spectroscopy could not have been used, briefly explain why.
My book says this compound is not aromatic because it possesses an allene group , which is C=C=C. I dont see where the allene is, can someone show me? I'm confused about how the radical is counted as a C?
Hi, I'm studying and I was wondering if you could explain to me why the drawn answer is the correct answer for this box problem and why the group would not be added on the other benzene ring. Thanks!
Thank you. Can you let me know why you number the methyl as the 1st carbon in problem A, but you number the ethyl as the first carbon in problem B-is it because you have two methyls in problem A? Can you explain the rule.
I have the following data from an NMR scan. Five peaks; a doublet at about 0.8ppm (6H) a small single septet at about 1.5 ppm (1H), a triplet at 1.6 ppm (2H(, a singlet at about 2.1 ppm (3H), a triplet at about 4.4 ppm (2H). The molecular formula is C7H14O2. I calculated a degree of unsaturation of 1. I have tentatively identified the compound as methyl-4-methylbutanoate. I would appreciate any comments you care to make. Thank you.
2) Draw the ECSF structures of CH3CH20° (ethoxide ion) and CH3CO2° (acetate ion). Why is ethoxide a SB but acetate a WB? (As it turns out, both are GNs) Redraw CH3CH200 (ECSF) Why SB? Redraw CH3CO2º (ECSF) Why WB?
