I REALLY need help PLEASE. The compound we're dealing
with is 4-tert-butylcyclohexanone. Can anybody explain to me why
carbons 5 AND 6 appear at the same signal? I get why carbons 5
would appear at the most infield signal, but why carbons 6? I have
drawn the structure and labeled the carbons and peaks:

Can anybody help me decipher the compound that produced this
carbon NMR and proton NMR? From the qualitative tests done in lab,
I know that the molecule is a ketone. I think the compound has
3,6,or 9 distinct carbons. Note that the cluster of three signals
on the carbon NMR is due to the solvent used (this was mentioned in
my lab notebook and was told that it was not due to my

Please help identify the
organic compound using mass spec, ir spec, CNMR, and HNMR.
From looking at the mass spec, I believe the molar mass of the
uknown organic compound to be 122 g/mol
From looking at CNMR, I believe there are at least 5 carbons for
each of the 5 peaks. I recall from class that there can be more due
to symmetry, but am not certain how to tell.
