Question
given the following info please provide a strucutre, the one I gave is incorrect.

Transcribed Image Text:Compound E has a molecular formula of C,H,0,. What is the Unsaturation Number (UN) or Double-Bond
Equivalent (DBE)?
UN/DBE:
5
Revealed Answer
Examine the IR spectrum provided for compound E.
Based on the molecular formula, the UN/DBE you calculated, and the IR spectrum, check all the functional groups that
are definitely not present in compound E?
O alcohol
v amine
aldehyde
O ketone
ester
O carboxylic acid
V nitrile
O benzene ring
alkene
O alkyne
O ring
Devealed AneIaer
Examine the 13C and 'H spectra of compound E.
All the proton signals are above 5 ppm.
What fragment would acount for that and the UN/DBE that you calculated earlier?
O cyclohexyl ring
benzene ring
tert-butyl group
alkene
alkyne
Revealed Answer
The singlet at 11 ppm is characteristic of which functional group? (Hint: two words, spelling counts!)
functional group: carboxylic acid
Revealed Answer
Draw a molecule that combines both of the fragments from the first two questions.
What is the molecular formula of the molecule you just drew? (Use the given format: CXHYOZ, where X, Y, and Z
are numbers.)
molecular formula: C,H,0,
Revealed Answer
The difference between the formula you just wrote out and the molecular formula of compound E is one atom. That atom is
part of the functional group that also accounts for the singlet at 5.4 ppm in the 'H NMR spectrum. What is the name of that
functional group?
name of the functional group: alcohol
Revealed Answer
Draw the structure of compound E.
Incorrect
O D O O
