When a central atom is involved with 3 sigma bonds, the orbitals will align themselves as far apart as possible around the central nucleus as illustrated here. Thebond angles are 120◦. There is one s orbital and 2 p orbitals. The orbitals aresp2hybridized, the geometry is trigonal planar. It is all on the same plane. An example would be AlBr3.



so percentage of s character= 33 percent
