lesson learnt today.
when the data booklet says R-group, they mean anything
like carbonyl or ether or whatever.
so -CO2CH2CH3 gives a delta reading of about 4. which is correct.
because the functional group directly adjacent to the alkyl chain is an ether.
not an ester.
and RCOOH gives an extremely high value
only with a labile proton.
lesson learnt: -CH2CH3 is not a labile proton.
ah well.
better now than later.
