sorry, i didn't include more information..
from my IR, it can be concluded
that it is not alkynes, alkenes, alcohol, secondary amide, nitro
it can be ester, ketone, aldehylde, tertiary amide, aromatic, alkane, alkyl halide
and then my next step was to look at this nmr, which is about deciding how many hydrogens there is, but our teacher did go in depth with the multiplet multiplicity. i understand the single, double, triple, quartet multiplicity, but not the multiplet one.
it can be concluded that it is not a C=OOH, since it doesnt go beyond 10,
nor a O=C-H (not sure the proper name for this),
nor aromatic,
nor C=C-H (alkene),
nor RCH2O, RCH2X, RCH2N (not sure of the names of these)
it could be
C (triple bond)CH,
=CCH2R,
cyclohexane-CH2R,
RCH2C=O,
hydrocarbons of R-CH3, R-CH2-R, R3CH
and then i would proceed to my mass spec, which i can only come to the conclusion of it being 154g/mol as the molecualr weight
