Question

how many NMR signals
​

Answer 1

Answer:

There are three signals because there are three sets of equivalent protons. The positions of the signals in an NMR spectrum are based on how far they are from the signal of the reference compound. This information tells us the kind of proton or protons that are responsible for the signal
