उत्तर
sp3, tetrahedral
Explanation:
Boron has die electronic configuration: 1s2 2s2 2px1 2p0 y 2p0z
In the excited state, 2s-orbital electrons are impaired and one electron is shifted to a p-orbital. Now, hybridisation occurs between one s-and three p-orbitals to give sp3 hybridisation and tetrahedral geometry.
