Answer

First Proposed Lewis Structure: [Cl—O:]⁻

Explanation:

Step 1: Calculate total valence electrons

Cl has 7 valence electrons, O has 6, and the ion charge is -1.
Total = (7 + 6 + 1 = 14).
The structure shows 14 valence electrons (2 bonding + 12 non-bonding), which is correct.

Step 2: Check octet rule

Both Cl and O have 8 valence electrons (2 bonding + 6 non-bonding).
Octet rule is satisfied for all atoms.

Answer:

Yes.

Second Proposed Lewis Structure: H═Br

Explanation:

Step 1: Calculate total valence electrons

H has 1 valence electron, Br has 7.
Total = (1 + 7 = 8).
The structure shows 8 valence electrons (4 bonding + 4 non-bonding), which is correct.

Step 2: Check octet rule

H can only have 2 valence electrons (violates with 4 from double bond).
Br has 6 valence electrons (4 bonding + 2 non-bonding), not 8.
Octet rule fails for both H and Br.

Answer:

No, it has the right number of valence electrons but doesn't satisfy the octet rule.
The symbols of the problem atoms are: H, Br

Third Proposed Lewis Structure: :O—C—O:

Explanation:

Step 1: Calculate total valence electrons

C has 4 valence electrons, each O has 6.
Total = (4 + 6 + 6 = 16).
The structure shows 16 valence electrons (4 bonding + 12 non-bonding), which is correct.

Step 2: Check octet rule

C has 4 valence electrons (4 bonding, no non-bonding), not 8.
O atoms have 8 valence electrons each (2 bonding + 6 non-bonding), which is satisfied.
Octet rule fails for C.

Answer:

No, it has the right number of valence electrons but doesn't satisfy the octet rule.
The symbols of the problem atoms are: C
