Question

Determine the electronic and molecular geometry of the following molecules. Use lines for shared electrons and dots for individual electrons.

C2H4

Cl2O

SO4^2-

NO3-

SO3

PH4^+

Answer 1

ion-------------------moecular geometry---------------------------electronic geometry

SO4^2------------------------tetrahedral-------------------------------------tetrahedral

NO3^---------------------------trigonal planar-----------------------------------trigonal planar

SO3-------------------------trigonal planar------------------------------------trigonal planar

PH4^+-----------------------tetrahedral----------------------------------------tetrahedral

C2H4---------------------trigonal planar-----------------------------------------trigonal planar

Cl2O-------------------bent shAPE------------------------------------------------tetrahedral

if the central atom surrounded by three pairs of electrons ,electronic geometry is trigonal planar

if the central surrounded by four pairs of electrons ,electronic geometry is tetrahedral

if the central surrounded by four pairs of electrons ,in that two are bond pair and two are lone pair molecular geometry is bent shape
