Solutions

Expert Solution

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
