Apart from the fact that between the two structures, only cyclohexe-4-ene-cis-1,2-dicarboxylic acid has the OH group shown on the IR spectrum. In what other majors way will the IR spectrum of cyclohex-4-ene-cis-1,2-dicorboxylic anhydride differ from the IR spectrum of cyclohexe-4-ene-cis-1,2-dicarboxylic acid?

The COOH peak will be shorter, broadened, and shifted to a shorter wavelength.
