What functional group is present in the reactants (isobutanol, sulfuric acid, Dichloromethane, sodium carbonate) but not in the ester? What wave number range in the IR spectrum does the peak appear and what does it look like?

4. Give the structure of each of the following compounds. a) a six-carbon alkane whose proton NMR consists of 1 singlet. b) a six-carbon alkene whose proton NMR consists of 1 singlet c) a nine-carbon alkane whose proton nmr consists of 2 singlets.

3.What peaks would expect to find for you Vs, cie'thy) amine thy) in the InfraRed' spectrum? +-butyl 'amine us. n-butyl amine

i need help making a proton and carbon nmr table for salicylaldehyde

Look at the three infrared spectra in Figures C to E and answer the following questions (a)  Are any of the spectra that of an alcohol? If so, which? What absorption pattern(s) at what wavelength(s) identifies an alcohol? (b)  Are any of the spectra that of a compound containing a benzene ring? If so, which? What three absorption patterns at what wavelengths show that a compound has a benzene ring? (c) Are any of the spectra that of a compound containing only carbons and hydrogens? If so, which? Benzene rings contain only carbons and hydrogens. Might the spectrum or spectra you chose for your answer above indicate a benzene ring? (Tell what absorption patterns are present or not present that would support your answer.)

please help?
