Answer #1

24)

Formal charge = ( Number of valence electrons on atom) -(non-bonding valence electrons+ bonding electrons/2)

For N-N-S

Formal charge: 5-(2+6/2) = (0) , 5-(0+8/2) = (+1) , 6-(6+2/2)= (-1) for N, N, S respectively

We have to chose the structure whose formal charges closest to zero i.e as low as possible

option B is the right answer.

    WHATS THE ANSWER? When drawing resonance structures, the most stable resonance structure is the one in which: O All atoms have a formal charge. O If there are formal charges, like charges are as close as possible. O Negative formal charges are on the least electronegative atoms. O Positive formal charges are on the least electronegative atoms. Next

    Writing Lewis Structures d. Because oxygen is more electronegative than nitrogen, it is more likely to have a negative formal charge. Which structure would then be the best description of N,O? e. Are the structures that have the N-O-N bond skeleton resonance forms of the structures with the N-N-O skeleton? Explain. 4. Hydrogen isocyanide, HNC, will convert to hydrogen cyanide, HCN, over time. Use their Lewis structures to explain this.

    #1 and #2 please. QUESTION 1 Check ALL that are true of formal charges. Formal charge can be used to determine the best resonance structure. Formal charges of zero are most preferable. A more negative formal charge should go on a more electronegative atom. A formal charge of -2 is better than a formal charge of +1 for any atom, because negative formal charge is better than positive formal charge. QUESTION 2 Check ALL that are true of resonance structures...
