Compound A: C6H14O
I've gathered that the Unsaturation Number is 0, so there is no double bond or ring present. (I've also attached the IR and NMR spectra on the bottom.)
But I'm having a hard time answering the following questions.
Compound A: C6H14O I've gathered that the Unsaturation Number is 0, so there is no double...
Compound F has a molecular formula of C9H8O. What is the
unsaturation number; Functional groups that are ppossibly present
in compound F?
I keep getting this question wrong, can anyone help me?
7 of 29 Incorrect Question 27 of Map Compound F has a molecular formula of CgHgO. What is the Unsaturation Number (UN) or Double-Bond Equivalent (DBE)? Number Examine the IR spectrum provided for Compound F Based on the molecular formula, the UN/DBE you calculated, and the IR spectrum,...
NMR Help please!
Based on the molecular formula and the UN/DBE you calculated, check all the functional group that could be present in compound B? Examine the IR spectrum provided for Compound B. The peaks below 1500 cannot be used to make any structural assignments because they are i fingerprint region. There are the two important peaks in this IR spectrum, What is each peak most likely due to? Earlier, using the molecular formula and the UN/BE, you came up...
lastly propose a strucutre for compound E
Compound F has a molecular formula of CgHgO. What is the Unsaturation Number (UN) or Double-Bond Equivalent (DBE)? Examine the IR spectrum provided for Compound F. Based on the molecular formula, the UN/DBE you calculated, and the IR spectrum, check all the functional groups that are possibly present in compound F? Examine the 13C and 1H spectra of Compound F. All the proton signals are above 6 ppm. What fragment would account for...
c) all the proton signals are above 5ppm. what fragment would
acount for that and the UN/DBE that you calculated earlier?
- cyclohexyl ring
- benzene ring
- tert-butyl group
- alkene
- alkyne
d) the singlet at 11ppm is charateristic of which functioanl
group? (hint: 2words, spelling counts)
e) draw a moleculate that combines both of the above
fragments.
Compound E has a molecular formula of C7H6O3. What is the Unsaturation Number (UN) or Double-Bond Equivalent (DBE)? Examine the...
