a) CH3I type of molecule is AX4 ; so there are 4
electron pair
and no lone pair for the central C atom: Hence electron geometry
and molecular
geometry are same
electron geometry : tetrahedral
molecular geometry : tetrahedral
(b) ClF3 :Type of molecule is AX3N2. Central atom Cl
has 3 bond pairs
and 2 lone pairs.
electron geometry : Triagonal bipyramidal
molecular geometry: T.shapped
(c) H2S : Type of molecule is AX2N2 ; that means 4
electron pairs
electron geometry : tetrahedral
molecular geometry : bent
(d) SO3 type of molecule : AX3 ; so there
are 3 electron pair no lone pair for the central S atom:
Hence electron geometry and molecular geometry are same
electron geometry : traigonal planar
molecular geometry : traigonal planar
(e) SO42− type of molecule is AX4 ; so there are 4
electron pair
and no lone pair for the central S atom: Hence electron geometry
and molecular
geometry are same
electron geometry : tetrahedral
molecular geometry : tetrahedral
