How many signals would you expect to find in the proton-decoupled 13C spectra of the following isomeric compounds?

Pls explain too

How many peaks would the 1H NMR spectrum of the following molecule have?

Which one of the following pieces of information cannot be obtained from an infra-red spectrum? * the presence of C=0 bonds the framework of compound the presence of O-H bonds the identity of a compound through comparison with other spectra

8. Sketch the off-resonance-decoupled 1³C spectra of the following compound. H H C C-H H The splitting pattern of off-resonance decoupled spectrum indicates the number of protons attached to the carbon. 13C nuclei are split only by the protons attached directly to them. The N + 1 rule applies: a carbon with N number of protons gives a signal with N + 1 peaks (e.g. carbon atom with one proton appears as a doublet; carbon with two attached protons gives a triplet etc.) • Carbon atoms with more hydrogens absorb more strongly.

I need help calculating the NMR chemical shifts for this compound.

In a proton NMR spectrum, indicate the number of peaks and their multiplicity for the following compounds: CH3 - CH2 - CO - CH3 para-chloromethylbenzene
