Answer #1


a) APT is proton testing for only hydrogens not for carbons

b) MRI => magnetic resonance imaging uses the radiowaves

c) HETCOR => on one axis Carbon nmr values and then on the other axis H nmr values are coupled and forms this 2D nmr spectra hetero correlation spectroscopy

d) DEPT => it is used identify the types of different carbons not for hydrogen atoms

e) COSY => on one axis H nmr values and then on the other axis H nmr values are coupled and forms this 2D nmr spectra it is correlation spectroscopy

answer => c) HETCOR

Compound B contains carbon, hydrogen and oxygen only. Its mass spectrum contains a molecular ion peak at m/e = 102 (relative abundance 35%) and an M+1 peak at m/e 103 (1.5%). Calculate the number of carbon atoms in the molecule, and hence deduce the number of oxygen atoms it contains, and its molecular formula.
