Question

Considering IR spectroscopy, which of the following statements is incorrect?

 

Question 20 options:

 

Primary amines produce two signals resulting from symmetric stretching and asymmetric stretching
 

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
 

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
