Question

decide whether these proposed lewis structures are reasonable. proposed lewis structure is the proposed lewis structure reasonable? \\:cl - o\\:⁻ 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: cl :o: 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: c h - h - o 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: h, h * 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 for [Cl - O]^-

Chlorine has 7 valence electrons, oxygen has 6 valence electrons, and there is an extra electron due to the negative charge. So, \(7 + 6+1=14\) valence electrons. In the structure, there are 14 electrons shown. But Cl has only 6 electrons around it instead of 8, violating the octet rule.

Step2: Calculate valence - electrons for Cl - C - Cl with O above C

Carbon has 4 valence electrons, each chlorine has 7 valence electrons, and oxygen has 6 valence electrons. So, \(4+2\times7 + 6=24\) valence electrons. The structure has 24 electrons shown. But carbon has only 6 electrons around it instead of 8, violating the octet rule.

Step3: Calculate valence - electrons for H - H - O

Hydrogen has 1 valence electron each and oxygen has 6 valence electrons. So, \(2\times1+6 = 8\) valence electrons. The structure has 8 electrons shown. But the first hydrogen has 2 electrons and the second hydrogen has 2 electrons, and they are bonded in a way that violates the normal bonding pattern (hydrogen should only form one bond typically), and also the structure is not a valid Lewis structure as written, violating the octet - like rules for the overall structure.

Answer:

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