Which orbitals are involved in dsp³ hybridisation?

1. d(x²-y²), d(z²) orbitals are involved in dsp³ hybridisation.
2. d(xy), d(xz) orbitals are involved in dsp³ hybridisation.
3. d(yz), d(z²) orbitals are involved in dsp³ hybridisation.
4. d(x²-y²), d(xz) orbitals are involved in dsp³ hybridisation.

Correct answer: d(x²-y²), d(z²) orbitals are involved in dsp³ hybridisation.

Solution

In dsp³ hybridisation, the orbitals involved are one d(z²), one s, and three p orbitals. The d(z²) orbital is specifically used because of its symmetry, which aligns well with the trigonal bipyramidal geometry.
