Question
Answer # 20 using 14-19 I think its b but not sure
Based on the following IR spectrum, which functionality does the unknown compound contain? a carboxylic acid a carbonyl an amide an alcohol a nitrile Based on the IR spectrum in question 14, which additional functionality does the compound contain? an alkyne an alkene an ether a tertiary amine an alkane Based on the 1H NMR spectrum below, how many methyl groups a: unknown compound that gave rise to the spectrum one two three four zero Bssed on tl:e 1H NMR spectrum in question 16, how many methylene groups are the unknown compound that gave rise to the spectrum? (remember, a methylene is -Ch2-). one two three four zero Based on 1H NMR spectrum in question 16, the compound must contain: adi-substituted benzene ring with substitution at the 1- and 4-positions a mono-substituted benzene ring a tri-substituted benzene ring a di-substituted benzene ring with substitution at the 1- and 2-positions none of the above Based on the 1H NMR spectrum question 16, the compound also must contain: an ethyl ether a methylene connected to an aromatic ring an alcohol connected to an aromatic ring a methylene connected to an alcohol none of the above Based on the information provided in questions 14-19, the structure of the unknown compound is:
Explanation / Answer
