Question
1) answer to question #16. I think there are two methyl groups but I am unsure.
2)how many methylene groups are there? I think the answer is 1 methylene group
3)based on the H NMR the compound must also contain :
a)an ethyl ether
b)a methylene connected to aromatic ring
c) an alochol connected to an aromatic ring
d) a methylene connected to an alcohol
e) none of the above.
4) last question, what is the structure? I think the structure is B but i am unsure.
Based on the 1H NMR spectrum below, how many methyl groups are in the unknown compound that gave rise to the spectrum? one two three four zero a methylene connected to an alcohol none of the above Based on the information provided in questions 14-29, the structure of the unknown compound is:Explanation / Answer
1. 2 because there are two different 3H spectrums.(3H is mentioned twice, it makes it easier to understand, it also means that if there is a s, that means that there are no adjacent hydrogens/ if there is a q, that means that there are 3 adjacent hydrogens to the Carbon (probalby a methyl group)
2. 1 because there is one 2H specrum
3. e none of the above. There are no ethyl ethers, or methylenes, or alcohols in this structures
4. B
Trust your judgement, your thinking on your notes were correct. Goodluck, hope this helps you :)
