Question 15: Please answer part a, b, and c Draw the Lewis structure of the missing reactant. Make sure to include lone pairs and non-zero formal charges. NH₂ + ? →> NH3 + CH3CH₂O Draw the Lewis structure of the missing reactant. Make sure to include lone pairs and non-zero formal charges. NHA + ? →>> NH3 + CH3CH2OH Draw the Lewis structure of the missing reactant. Make sure to include lone pairs and non-zero formal charges. OH + ? →>> H2O + CH3CH₂O

An incomplete Lewis structure is shown below. The structure only shows the atoms and how they are connected. The molecule has a net charge of zero. H Н—N—С- -о—с—Н H H Complete the Lewis structure giving all atoms full octets. If there is more than one way to do this, draw resonance structures showing all possibilities. If not, just draw one Lewis structure. Be sure to write in any non-zero formal charges. Click and drag to start drawing a structure.

Draw the best Lewis structure for  CHBr2COO− . Be sure to include lone pairs and assign a formal charge for any atom with a non-zero formal charge.

-draw the possible resonance structures of IO3^2- ion. -the experimental bond length of P and O bond in PO4^3- ion is in between the bond lengths of P=O and P-O.what is the reason behind this?. -draw the possible resonance structures of C3h3^- ion and on each sructure assign formal charge on each atom.

Draw the Lewis structure of the missing reactant. Make sure to include lone pairs and non-zero formal charges.

+ Write a Lewis structure for the ammonium ion, NH4™. Explicitly draw all H atoms. Include all valence lone pairs in your answer. Include all nonzero formal charges. Do not use the square brackets tool in your answer. P aste opy [*

2- a. Write a Lewis structure that obeys the octet rule for the following species. Assign the formal charge for the central atom of SO42. If multiple resonance structures exist, use one that does not involve an expanded valence. Formal charge: 3- b. Write a Lewis structure that obeys the octet rule for the following species. Assign the formal charge for the central atom of PO4³. If multiple resonance structures exist, use one that does not involve an expanded valence. Formal charge:

CO3²- Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. Show the formal charges of all atoms in the correct structure. To change the symbol of an atom, double-click on the atom, and enter the letter of the new atom.

The carbonate anion, CO32- , is a resonance hybrid. Draw all of the important resonance structures for this molecule. If an atom has a nonzero formal charge, be sure the formal charge is shown clearly in the structure. Use the resonance structures to calculate the average formal charge on each O atom (which are all equivalent in the "true" structure). [Note: all of the important contributing resonance structures have octets around each atom that desires an octet.]
