प्रश्न
Predict the shapes of the following molecules on the basis of hybridisation.
\[\ce{BCl3, CH4 , CO2, NH3}\]
Advertisements
उत्तर
In \[\ce{BCl3}\], the geometry is trigonal planar is due to sp2 hybridisation.
The shape of \[\ce{CH4}\] is tetrahedral due to sp3 hybridisation.
\[\ce{CO2}\] show linear shape because of sp hybridisation.
The geometry of \[\ce{NH3}\] is pyramidal shape and has sp3 hybridisation.
