Question

(10 pts) Draw the Lewis structures for each compound and determine formal charge, hybridization, electron and molecular geometries on central atom. a) HzAs03 b) CIF, c) CIO

Answer 1

H₃AsO₃ will be having a tetrahedral electron geometry and trigonal pyramidal molecular geometry with sp³ hybridization of As as it contains 3 bond pairs and one lone pair around the central atom: The lewis structure is as follows: The formal charge is also shown

Ho— As-OH

arsenous acid

  

The molecular geometry will be square pyramidal and the hybridization will be sp^₃d2 as it contains five bond pairs and one lone pair.

c) The molecular geometry is bent and the hybridization is sp3.
