Grade 11Physical Chemistry

I want 3D structures of molecules to understand the shapes of molecules fully.The shapes for which I want 3D structures are --

1.Triangular Planar

2.Tetrahedral

3.Trigonal Bipyramidal

4.Octahedral

5.Pentagonal Bipyramidal

Please provide me structures.Please*infinity

Dear nitin,

Total Number of electron pairs	Arrangement of electron pairs	Number of bonding pairs of electrons	Number of lone pairs of electrons	Name of Shape	Bond Angle	Examples
not applicable	linear	1	not applicable	linear	180^o	H₂, HCl
2	linear	2	0	linear	180^o	CO₂, HCN
3	trigonal planar	3	0	triganol planar	120^o	BCl₃, AlCl₃
4	tetrahedral	4	0	tetrahedral	109.5^o	CH₄, SiF₄
		3	1	trigonal pyramidal	<109.5^o (bond angles in ammonia, NH₃, are 107^o)	NH₃, PCl₃
		2	2	bent	<109.5^o (bond angles in water, H₂O, are 105^o)	H₂O, SCl₂
5	trigonal bipyramidal	5	0	trigonal bipyramidal	120^o in the trigonal planar part of the molecule, 90^o for the others	PCl₅
6	octahedral	6	0	octahedral	90^o	SF₆
