What is wrong with this Lewis dot structure for the H₂CO molecule? :Ö: 0- I H-C-H

Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure :: : Cl - : 0: :0: :Z: C. C= : Z: N N Cl: 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 doesn't 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 doesn't satisfy the octet rule. The symbols of the problem atoms are:* 0 Yes. 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:* * If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "0,0". X 5

Hydrogen cyanide contains three total atoms, one each of carbon, nitrogen, and oxygen. Which Lewis structure for hydrogen cyanide is correct? O O O H=N=C H-C=N: H-C-N: :Z: H-N-C: H-N=C: H=C=N

A newly discovered element Lm has 3 valence electrons. How many total valence electrons are in LmF3 molecule, a molecule that Lm forms with fluorine?  Draw a valid Lewis Structure for the molecule LmF3 that Lm forms with fluorine and use your Lewis structure to determine the number of lone pairs of electrons around the central Lm atom in this molecule.  What is the formal charge of Lm in LmF3? (Number and sign of formal charge) What is the hybridization of Lm according to the hybrid orbital model?
