The following 2 spectra belongs to 1 compound, what do you need to do is 1. Draw the assigned carbon splitting in the IR spectrum and give a brief explanation to it to support your answer 2. identify the m/z values (atleast 4) and structure of the compound in the mass spectrum and give a brief explanation to it to support your answer
Considering IR spectroscopy, which of the following statements is incorrect? options: Concentrated alcohols give rise to broad signals while dilute alcohols give rise to narrow signals Carboxylic acids exist as dimer due to hydrogen bonding and thus produce a narrow signal at 3600 cm-1 and a characteristic signal due to C=O at 1700 cm-1 C=O bonds produce strong signals in an IR spectrum while C=C bonds often produce a weak signals Symmetrical C=C bonds and C≡C bonds do not produce signals Primary amines produce two signals resulting from symmetric stretching and asymmetric stretching
