Based on the following IR and NMR is this benzoic acid, 2-methoxybenzoic acid or o-toluic acid?...
What would be difference between the IRs of p-toluic acid (starting material) and 4- (bromomethyl)benzoic acid (product)? (You don’t need to look up the IR of p-toluic acid, just think about what is changing between the starting material and product). Why is IR not a good way to verify that you made product?
Which of these compounds are soluble in water? Benzoic Acid 4-t-butylphenol 2-chlorobenzoic acid 1-napthol o-toluic acid
C. Interestingly, when compared to benzoic acid, p-methoxybenzoic acid is less acidic and m- methoxybenzoic acid is more acidic. Please explain how the location of the methoxy groups influences the pka of each isomer relative to benzoic acid using drawings and a minimum amount of words. TIP: How stable is each conjugate base? What is or isn't stabilizing it? TIP #2: EAS/Aromaticity has nothing to do with it. Meo OME increasing acidity

Out of the four acids: A.) o-toluic acid B.) benzoic acid C.) salicylic acid D.) p-hydroxybenzoic acids Which one(s) would you expect to be more readily soluble in ether? Which one(s) would you expect to be less readily soluble in ether? Justify your answer.
I think the compound is p-toluic acid, but I just need help analyzing the H-NMR, C-NMR, and the IR spectrums.

Question 2 of 2 that is MARKED for the NMR/IR prelab. You can edit this one until the lab starts. You are given this information about a compound: Then index of hydrogen deficiency (IHD) = 4. NMR shows a TH signal at 6 = 2.35 ppm corresponding to a CH3 group. NMR shows a complex multiplet corresponding to 5 H between 7-8 ppm. From this the structure is most likely: Select one: a. Toluene = CH3-C6H5. O b. Phenol =...
What acidic compound is shown based on the 13C NMR and 1H NMR spectra? I am having trouble pinpointing which acid this actually is, since I do not have a melting point associated. I attached a list of the possible ones it could be, my guess is 4-methylbenzoic acid, since there are four peaks in the H NMR, but am not 100% confident. The triplet signal shown in the top 13C spectra with ~77 ppm values are CDCL3. This was...
