Predict the shapes of the following molecules on the basis of hybridisation.

BCl3, CH4,CO2, NH3


In BCl3, the geometry is trigonal planar is due to sp2 hybridisation.
The shape of CH4 is tetrahedral due to sp3 hybridisation.
CO2 show linear shape because of sp hybridisation.
The geometry of NH3 is pyramidal shape and has sp3 hybridisation.
