A.     The C–O bond lengths are equal in propanoic acid, ${{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}{\text{COOH}}$.

B.     The C–O bond length in carbon dioxide, ${\text{C}}{{\text{O}}_{\text{2}}}$, is longer than the C–O bond length in methanol, ${\text{C}}{{\text{H}}_{\text{3}}}{\text{OH}}$.

C.     The C–O bond length in carbon dioxide, ${\text{C}}{{\text{O}}_{\text{2}}}$, is longer than the C–O bond length in carbon monoxide, CO.

D.     The C–O bond lengths are equal in ethyl ethanoate, ${\text{C}}{{\text{H}}_{\text{3}}}{\text{COO}}{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}$.
