For each molecule/ion shown, please draw the Lewis structure and indicate the formal charge on each atom. If equivalent structures exist, draw all possible "best structure" resonance structures. 1. PO. 2. Na CO 3. HCO 4. SCN- (draw 3 "best" resonance structures here)
Draw three-dimensional depictions of the following molecules. For each molecule provide theoretical bond angles, shape, and electron group geometry (ie octahedral, tetrahedral, bent, etc.). For each molecule, provide all possible structural and geometric isomers. If the molecule/ion possesses resonance structures, draw all relevant structures? What is the point group of each structure? If the compound is chiral, draw its enantiomer. NiCl2(NH3)2 (tetrahedral) PCl2F3 NO3-
1. The formal charge is the "charge" an element would have in a molecule or ion if all of the bonding electrons were shared equally between atoms. We can draw three inequivalent Lewis structures for the tellurite ion , TeO32-. The concepts of formal charge and electronegativity can help us choose the structure that is the best representation. 1. Assign formal charges to the elements in each of the structures below. Note: Count oxygen atoms starting from the left for each structure.2. The best...
a. Draw the Lewis dot structure of sulfite ion, starting with the number of valence electrons b. Calculate the formal charge on each of the atoms. Which is the best structure? c. Are there any resonance structures for the best Lewis structure? If so, draw them? d. What is the bond order of bonds in SO3 ^2-? e. Is the molecule polar or non-polar? If so why? f. What is the electron domain and molecular geometry? Name and draw both...
Review Part A Draw three resonance structures for sulfur tetroxide, SO4, whose connections are shown below. (This is a neutral molecule; it is not sulfate ion.) Assign formal charges to the atoms in each structure. O O 0—5—0 Sulfur tetroxide Draw all possible resonance structures by copying the skeleton shown. Edit bonds and charges to complete each resonance structure. Use the plus (S) and minus lone pairs of electrons will adjust automatically. ) charge buttons to indicate formal charges at...

34) For each of the following covalent compounds or polyatomic anions, 1) draw the best Lewis structure. 2) Include any equivalent resonance structures. 3) Name the molecular geometry. 4) Indicate if the molecule/ion is polar or non-polar (4 points each) a) XeF2 b) BrO4 c) SO32- d) SF4
Consider the compound whose formula is shown below. C2H40 1) Calculate the total number of valence electrons. 2) Calculate the number of bonds in the molecule. 3) Draw all possible skeleton structures representing all possible isomers. Cyclic isomers are allowed. 4) For each skeleton structure, complete its Lewis dot structure showing all electron pairs. 5) Draw resonance structures for each isomer. If a resonance structure cannot be drawn, explain why. 6) For each isomer, calculate the formal charge on each...
