Problem: Draw the Lewis structure for each compound.H3AsO4

FREE Expert Solution

Step 1: Arsenic (EN = 2.18) is less electronegative than oxygen (EN = 3.44) and hydrogen only forms 1 bond hence arsenic is the central atom.

Step 2: The total number of valence electrons present in H3AsO4


            Group             Valence Electrons

As       5A                   1 × 5 e5 e

H         1A                   3 × 1 e3 e

O         6A                   4 × 6 e24 e

Total:  32 valence e

Step 3: As will go in the center while H and O are terminal atoms.
