Document Summary

Identify the lewis structure resonance forms for po4 3- that minimizes formal charges. Based on this structure, what would be bond order of the phosphorous- oxygen bonds? a. ) The bond order is 2 for one, 1 for the others b. ) The bond order is 1 for all of them c. ) the bond order is 1. 5 for all of them d. ) the bond order is 5/4 for all of them e. ) none of these answer choices are correct. 5 bonds total; 4 areas ; so bond order=5/4. Which of the following would be expected to have the largest atomic/ionic radius? a. ) Rb+ c. ) kr d. ) br e. ) there is no way to predict which of these would have the largest radius. Rb+ and kr have same number of electrons, Rb have more atomic number- more force- smaller. Nh4+ -- nh3+ h+ weak acid but complete dissociate, so also a strong electrolyte.

3) write the Lewis dot structure for the following species. show all non-zero formal charges. if applicable, write other resonance forms of the structure

Draw three resonance structures for CO2. This species has its threeatoms bonded sequentially in the following fashion: O-C-O. Drawyour resonance structures so that the atoms in them are bondedtogether in this order. Select the most important resonancestructure for this species based on the formal charges on the atomsof the three resonance structures you have drawn. Now select thestatement from the multiple choices which is true about this mostimportant resonance structure.

In the most important resonance structure of CO2 :

a) The leftmost bond (between O and C) is a double bond.
b) The rightmost bond (between C and O) is a triple bond.
c) The formal charge on the leftmost (O) atom is -1.
d) The number of nonbonding pairs (lone pairs) of electrons on theleftmost (O) atom is 4.
e) The number of nonbonding (lone) pairs of electrons on therightmost (O) atom is 1.
