what is this compound, it has a mf of c6h12o i. imgur. com/gCgw0Hi. png
What may be the structure from the IR and H NMR data? This question is bugging me.
I don' remember enough about the assignments of wavelengths to be of any help with the IR and I haven't had any experience with the NMR relative to structure.
Okay, it just bugged me. I think I solved it, but two of the peaks for protons in the H NMR spectrum weren't split like I thought they would be, and so I wasn't sure when I gave the individual a final answer after several attempts.
"Just look at the graph," the player's agent said. "Phil's hits have doubled since last year. We are looking for a large raise and a long contract."
Look at the graph.

How can you redraw this graph so it appears that Phil's hits have quadrupled since last year.
a.
Use the same scale and make the top bar twice as thick as the bottom bar.
b.
Alter the scale so the top bar appears four times as long as the bottom bar.
c.
Both a and b.
d.
Neither a or b.
To determine the structure of a compound given its molecular formula (C6H12O) and spectral data (IR and H NMR), we need to analyze the information and make logical deductions.
First, let's tackle the infrared (IR) spectrum. The IR spectrum provides information about functional groups in a molecule based on the vibrations of bonds. By examining the peaks, we can identify some common functional groups.
Unfortunately, I cannot access external links such as the one you provided (imgur.com/gCgw0Hi.png). However, I can guide you on how to interpret the IR spectrum yourself.
1. Look for a broad peak around 3300-3500 cm-1: This indicates the presence of an -OH group (alcohol or carboxylic acid).
2. Check for strong, sharp peaks around 1700 cm-1: These indicate the presence of a carbonyl group (such as a ketone, aldehyde, or ester).
3. Look for peaks between 2800-3000 cm-1: These indicate the presence of C-H bonds (alkanes, alkenes, or aromatic rings).
By analyzing the IR spectrum for those characteristic peaks, you can narrow down the possible functional groups present in the compound.
Next, let's consider the hydrogen nuclear magnetic resonance (H NMR) spectrum. The H NMR spectrum provides information about the number and types of hydrogen atoms in a molecule and their chemical environment (chemical shift).
1. Look for the integration values: These show the relative number of hydrogen atoms represented by each peak.
2. Examine the chemical shifts: These give clues about the types of hydrogen atoms present. Common chemical shifts for different functional groups can be found in reference databases or textbooks.
By analyzing the integration values and chemical shifts in the H NMR spectrum, you can determine the types and number of hydrogen atoms in the compound.
Once you have gathered this information, you can use it to make logical deductions about the possible structure of the compound. Compare the functional groups and hydrogen environments deduced from the spectral data with the given molecular formula (C6H12O) to identify potential structures. Structural isomers with the same molecular formula but different connectivity are also worth considering.
If you are having trouble interpreting the spectral data, you may consult with a chemistry professor, a textbook, or online resources specifically aimed at helping to analyze IR and NMR spectra.
Remember, interpreting spectral data can be challenging and may sometimes require advanced knowledge and expertise in organic chemistry.
