Draw all resonance structures for the acetate ion, \( \mathrm{CH}_{3} \mathrm{COO}^{-} \). - Explicitly draw all \( \mathrm{H} \) atoms. - Include all valence lone pairs in your answer. - Do not include overall lon charges or formal charges in your drawing. - Do not draw double bonds to oxygen unless they are needed for the central atom to obey the octet rule. - Draw one structure per sketcher. Add additional sketchers by selecting \( \leftrightarrow \) in the drop-down menu Please note that "geometry" refers to the molecular or lonic geometry. A. The Lewis diagram for \( \mathrm{NO}_{2} \mathrm{~F} \) is: Recall that for predicting geometry, double and triple bonds count as only one electron pair. The electron-pair geometry around the \( \mathbf{N} \) atom in \( \mathrm{NO}_{2} \mathrm{~F} \) is There are Ione pair(s) around the central atom, so the geometry of \( \mathrm{NO}_{2} \mathrm{~F} \) is B. The Lewis diagram for \( \mathrm{CO}_{2} \) is: Recall that for predicting geometry, double and triple bonds count as only one electron pair. The electron-palr geometry around the \( \mathrm{C} \) atom in \( \mathrm{CO}_{2} \) is There are Ione pair(s) around the central atom, so the geometry of \( \mathrm{CO}_{2} \) is Draw a Lewis structure for \( \mathrm{SiCl}_{4} \) in which the central SI atom obeys the octet rule, and answer the following questions based on your drawing. The number of unshared pairs (lone pairs) on the central SI atom Is: The central Si atom forms single bonds. The central Si atom forms double bonds. 2 more groug attempte remaining Draw a Lewls structure for \( \mathbf{S F}_{2} \) In which the central \( \mathbf{S} \) atom obeys the octet rule, and answer the following questions based on your drawin The number of unshared pairs (lone pairs) on the central \( \mathbf{S} \) atom is: The central \( \mathbf{S} \) atom forms single bonds.

A model for \( \mathrm{GeH}_{4} \) Is shown in the chem3D window. \( \mathrm{GeH}_{4} \) has tetrahedral geometry. Rotate the molecule until you have a feeling for its three-dimensional shape. How many atoms are bonded to the central atom? If you take any three of the outer atoms, what shape do they define? Consider the bond angles at the central atom. Do they all have the approximately the same numerical value? What is the approximate numerical value of this angle? degrees. Are all four positions about the central atom equivalent, or is one of them different from the other three.
