QUESTION 1 Assuming that the octet rule is not violated, draw the Lewis structure of the most important resonance form of the

Answer 1

Answer #1

02.0

In the structure all atoms has 8 electrons around it.
So, octet rule is not violated.

The formula of formal charge is:
Formal charge = [# of valence electrons] – [electrons in lone pairs + 1/2 the number of bonding electrons]

O:
# of valence electrons for C = 6
Formal charge = 6 - (6+ 1/2 * 2)
= 6-7
= -1

As:
# of valence electrons for As = 5
Formal charge = 5 - (0+ 1/2 * 8)
= 5-4
= +1

Each O has formal charge of -1 and As has formal charge of +1
So, net charge on molecule is -3

Answer: A
