NO2+ has linear shape, due to sp hybrid state of N.
Determination of linear shape of molecule
- Molecular shapes can be predicted using Lewis diagrams and the VSEPR theory. Molecules that consist of three atoms (i.e. AX2) may be linear or bent.
- Linear molecular geometry would be empirically based upon an AX2 molecular formula with ‘A’ being the central element and X’s the attached substrates.
- The AXn is the most commonly used general formula. Molecules with a linear electron pair geometries have sp hybridization at the central atom.
