sumansumitha is rite.
some more about hybridisation..........
types:
1)sp -linear geometry -co.no=2 eg:C2H2
2)sp2 -trigonal planar -co.no=3 C2H4
3)sp3, -tetrahedral 4 CH4
dsp2 -square planar 4 Ni(CO)4
4)sp3d -trigonal bipyramidal 5 PCl5
5)d2sp3 or sp3d2 -octahedral 6 SF6
hope this helps
rate if satified
!!!!!!!!!!!!!!
