Question
1. Look again at the Lewis structures that you drew in questions 1 through 9 of this homework assignment and determine which of them exhibit resonance. (In other words, which of the following molecules exhibit resonance? Note: there is more than one answer and you must choose all of the molecules in the list that exhibit resonance.) Options: Cs2, PCl3, SO2, SO3, O3, NH3, BCl3, and IF5 2. Determine which of these molecules has a central atom that unavoidably violates the octet rule. Please note that NO3 has an odd number of electrons. But you must decide where the missing electron will be. Does the central atom violate the octet rule or do the oxygen atoms? Use formal charges to decide. (In the image it lists molecules that violate the octet rule but some of those are wrong). Options are SO3, SO2, PCl3, XeF2, NO3-, IF5, BCl3, CS2, and NH3 Thank you so much for your help!
Explanation / Answer
1. Cs2, SO2, SO3, O3,
2. SO3, SO2, XeF2, IF5, BCl3,
