Question

decide whether these proposed lewis structures are reasonable. proposed lewis structure is the proposed lewis structure reasonable? yes. no, it has the wrong number of valence electrons. the correct number is: no, it has the right number of valence electrons but doesnt satisfy the octet rule. the symbols of the problem atoms are: yes. no, it has the wrong number of valence electrons. the correct number is: no, it has the right number of valence electrons but doesnt satisfy the octet rule. the symbols of the problem atoms are: yes. no, it has the wrong number of valence electrons. the correct number is: no, it has the right number of valence electrons but doesnt satisfy the octet rule. the symbols of the problem atoms are: * if two or more atoms of the same element dont satisfy the octet rule, just enter the chemical symbol as many times as necessary. for example, if two oxygen atoms dont satisfy the octet rule, enter \o,o\.

Explanation:

Step1: Calculate valence - electrons of $O = O = O$

Oxygen has 6 valence electrons. For $O_3$, the total number of valence electrons is $3\times6 = 18$. In the given structure, each oxygen has 8 electrons around it (octet - satisfied), and the number of valence electrons is correct.

Step2: Calculate valence - electrons of $N - N$

Nitrogen has 5 valence electrons. For $N_2$, the total number of valence electrons should be $2\times5=10$. In the given structure, each nitrogen has only 7 electrons around it (not satisfying the octet rule), and the number of valence electrons in the structure is 8 (wrong). The correct number is 10.

Step3: Calculate valence - electrons of $Cl - C - Cl$ with $O$ above $C$

Carbon has 4 valence electrons, oxygen has 6 valence electrons, and chlorine has 7 valence electrons. The total number of valence electrons for $COCl_2$ is $4 + 6+2\times7=24$. In the given structure, carbon has only 6 electrons around it (not satisfying the octet rule), and the number of valence electrons is correct.

Answer:

1. Yes
2. No, it has the wrong number of valence electrons. The correct number is: 10
3. No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are: C
