Why are the major structures the ones where carbon has incomplete octets? Isn't the first rule for major resonance structures that the structure have as many full octets as possible?

Predicting the single-bonded molecular compounds formed by two elements.

Explain why acetic acid does not have any resonance structures while the acetate ion does ? How does this affect the bond order of these molecules ?

Consider the SO 3 molecule. How many valence electrons does the molecule have?   How many lone pairs of electrons are on the central atom?   How many lone pairs of electrons in total are on the substituent atoms?   How many resonance structures can be drawn for the molecule?  If the ion doesn't exhibit resonance, indicate "1" as only one structure can be drawn for the molecule.

Which of the following molecules contains at least one atom that has an expanded (hypervalent) octet?

Why do sodium ion and choride ion form a compound?   A) The energy of the formation of the negative chloride is overcome by the energy of the formation of the positive sodium ion.   B) The lattice energy between the positive sodium and the negative chloride ions overcome the  endothermic formation of the ions   C)The energy of the formation of the positive sodium ion is overcome by the energy of the formation of the negative chloride ion.   D) The energy of the formation of the positive sodium ion is canceled by the formation of the negative chloride ion.

Deciding whether a Lewis structure satisfies the octet rule Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure Is the proposed Lewis structure reasonable? O Yes. O No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. fä=ö The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule.
