Question

decide whether these proposed lewis structures are reasonable. proposed lewis structure is the proposed lewis structure reasonable? h - h - o - h+ 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: o = c = 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: 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 $[H - H - O - H]^+$

Hydrogen ($H$) has 1 valence electron and oxygen ($O$) has 6 valence electrons. The ion $[H - H - O - H]^+$ has 3 $H$ atoms and 1 $O$ atom. The total number of valence electrons should be $3\times1 + 6-1$ (due to +1 charge) = 8. In the proposed structure, there are incorrect bonding and electron - counting.

Step2: Calculate valence - electrons for $[:Cl = O:]^-$

Chlorine ($Cl$) has 7 valence electrons and oxygen ($O$) has 6 valence electrons. For the ion $[:Cl = O:]^-$, the total number of valence electrons is $7 + 6+1$ (due to - 1 charge)=14. The proposed structure has incorrect electron - counting.

Step3: Analyze $O = C = O$

Carbon ($C$) has 4 valence electrons and oxygen ($O$) has 6 valence electrons. The total number of valence electrons is $2\times6 + 4=16$. In the $O = C = O$ structure, each atom satisfies the octet rule. Carbon has 4 bonds (8 electrons around it) and each oxygen has 2 bonds and 2 lone - pairs (8 electrons around it), so the structure is reasonable.

Answer:

1. No, it has the wrong number of valence electrons. The correct number is: 8
2. No, it has the wrong number of valence electrons. The correct number is: 14
3. Yes.
