For planer BH3, the LUMO is an (A) antibonding orbital (B) Non bonding 1S (C) Non bonding 2P (D) bonding ?
Homework Answers
BH3 has B in sp2 hybridised state and hence we get three molecular orbitals , these sp2 hybrid orbitals of B will overlap with 3 1s orbitals or 3 Hydrogen atoms to form overall 6 molecular orbitals. Out of which first 3 orbitals are filled with 2e- each. Fourth orbital which is a vacant 2p orbital of B is LUMO ( least unoccupied molecular orbital).
