To determine which of the given molecular shapes is not correctly matched, we will evaluate each one based on the VSEPR (Valence Shell Electron Pair Repulsion) theory.

1. **XeO₃ – Trigonal bipyramidal**: This is incorrect. Xenon trioxide (XeO₃) has a pyramidal shape due to the presence of lone pairs on the xenon atom. The correct shape is trigonal pyramidal, not trigonal bipyramidal.

2. **ClF₃ – Bent T-shape**: This is correct. Chlorine trifluoride (ClF₃) has a T-shaped geometry because there are three fluorine atoms and two lone pairs on the chlorine atom.

3. **XeOF₄ – Square pyramidal**: This is correct. Xenon oxyfluoride (XeOF₄) features a square pyramidal geometry with four fluorine atoms and one oxygen atom around the xenon, along with one lone pair.

4. **XeF₂ – Linear shape**: This is correct. Xenon difluoride (XeF₂) has a linear molecular geometry owing to its two fluorine atoms and three lone pairs.

### Final Answer
**XeO₃ – Trigonal bipyramidal** is not correctly matched; it should be trigonal pyramidal.
