Assign the formal charge of each atom in each of the three resonance structures. On the basis of the formal charges and the electronegativities, identify the major resonance structure. с. Duour tho LOuris dot structure for each of the following molecules or ions. Determine

3. The following shows all resonance structures for the following molecule. a. Draw in all implied lone pairs. b. Draw in curved arrows that show the flow of electrons, making sure the arrows show the precise starting point and destination of the electrons. Label each arrow as: lp →→→л (p=lone pair) c. d. Rank the resonance structures from most stable to least based on the number of formal charges and atoms that lack an octet of electrons. ol-of-o. B A D d-d-d-o E C F G

1 What is the total number of valence electrons in the Lewis structure of ICl,"? electrons 2 Draw a Lewis structure for ICl,". • Do not include overall ion charges or formal charges in your drawing. If the species contains oxygen, do not draw double bonds to oxygen unless they are needed in order for the central atom to obey the octet rule. C opy aste Previous Next

Q16. Consider the compound SOCI2, thionyl chloride. (a) How many valence electrons are in this molecule? (b) Draw a valid Lewis dot structure for this molecule. (c) Calculate formal charges for each atom. (d) How many non-bonding electron pairs (lone pairs) are on the central atom? (e) Using VSEPR theory, determine the correct molecular shape/geometry for this molecule.

Consider the following incomplete structures. On your rough sheet, complete their correct Lewis structures (including minimizing formal charge) by adding electrons/bonds where necessary. Which statement below is true of the completed Lewis structures? Hint: Consider the potential for multiple bonds on the molecules and be sure to account for all valence electrons. The NOCI," exhibits both formal charges and resonance hybrids, while the BrOCI," exhibits resonance hybrids but no formal chargés None of these. The NOCI, exhibits formal charges but no resonance hybrids, while the BrOCI," exhibits both formal charges and resonance hybrids The NOCI, exhibits both residual formal charges and resonance hybrids, while the BrOCI, exhibits formal charges but no resonance hybrids At least one atom in each molecule exhibits formal charges, and the molecules have no resonance hybrids The BrOCI, exhibits formal charges but no resonance hybrids, while the NOCI, exhibits resonance hybrids but no formal…
