Find out shape and hybridisation of the following molecules ( PCl5, NH3, H2O, SF6 )
PCl5 : P(G.S)=1s22s22p63s23p3
P(E.S)=1s22s22p63s13p3
One s , three p & one d orbitals of same shell participate to give sp3d hybridisation.
Shape: Trigonal bipyramidal.
Figure-1 represents the shell diagram.
Figure-2 represents the shape .
NH3:N(G.S)=1s22s22p3N(E.S)=1s2
One s , three p participate to give sp3 hybridisation.
Shape: Pyramidal
Figure-3 represents the shell diagram.
Figure-4 represents the shape .
H2O:O(G.S)=1s22s22p4O(E.S)=1s22s22p2x2p1y2p1z
Two half filled sp3 hybrid orbital of Oxygen atom & s orbital of 2 Hydrogen atom overlap to form water.
Shape: V-shaped or distorted tetrahedral due to
lp−lp,lp−bp,bp−bp repulsion.
