Which of the Following Would You Expect to Have the Lower-Frequency

Question

Examlex · Accepted Answer

The Answer is The carboxylate anion (B)would show a lower-frequency C

The carboxylate anion (B)would show a lower-frequency C O stretch than the carboxylic acid (A).This is because it contains a significant resonance contributor in which the negative charge is localized on the other oxygen,as shown below.Therefore,the double bond in B is weaker (in fact,it is more accurately a bond with an order of 1.5 rather than a actual double bond),and a weaker bond corresponds to a lower frequency.
