How many NMR signals would you expect to see in 2 pentanone?
1) In the NMR spectrum, we note that there are 4 distinct peaks, so we know that in the molecule, there are four different types of hydrogens.
How many NMR signals does o xylene have?
e-xulene 1 o-xylene has 4 distinct resonances in “CNHR.
How many NMR signals does p-xylene have?
two signals
Each isomer of xylene produces a slightly different 1H NMR spectrum. The highly symmetric p-xylene produces two signals, one aliphatic signal due to the substituent methyl protons, and a second aromatic proton signal.
