Which of the following observations are useful in confirming that the product is

paracetamol, and not for example, unreacted 4-aminophenol? *

It may help to compare both spectra and structures when answering. You may select multiple answers.

Check all that apply.

Both spectra indicate the presence of a C-O bond

The paracetamol spectra shows absorbtion corresponding to a C=0 bond

The paracetamol spectra shows absorbtion corresponding to a C-N bond

The paracetamol spectra shows only 1 N-H bending and stretching signal

The 4-aminophenol spectra has less peaks

The 4-aminophenol spectra shows absorbtion corresponding to an O-H bond

The paracetamol spectra shows aromatic out of plane bending/n27.
