Answer

NO₂²⁻ has greater bond lengths compared to NO₃²⁻.

Work Step by Step

NO₂²⁻ has greater bond lengths compared to NO₃²⁻. In NO₂²⁻, one of the oxygen atoms carries a single bond with the nitrogen atom, whereas in NO₃²⁻, all three oxygen atoms have a single bond with the nitrogen atom. The repulsion between the oxygen atoms in NO₃²⁻ causes shorter bond lengths than in NO₂²⁻.
