Draw Lewis structures to determine which of the following
compounds exhibit resonance. Enter the letters corresponding to all
those compounds which exhibit resonance. (If you find that choices
A, C, and F all have resonance and the others do not, for example,
you would enter ACF as your answer. Make sure the letters you enter
are in alphabetical order, with no spaces or commas separating
them.)
2. Draw Lewis structures to determine which of the following compounds exhibit resonance. Enter...
1. Write the "best" Lewis structure (minimize formal charge, maximize number of resona structures) for the following species. Include formal charges on all atoms having any and give resonance structures. When appropriate, expand the octet to reduce formal charges and gain resonance structures. Give the electronic and molecular geometries for each and determine i they are polar or nonpolar. NO2 SO32- PO43- 2. Use formal charge to determine which Lewis structure is better: H-5--H H- -3-H
with regard to resonance structures that are drawn for a real species which of the following statements is/are NOT true? A.) resonance structures are real molecules that co-exist in equilibrium with each other. B.) resonance structures differ in the location of their electrons, not the position of their atoms. C.) resonance structures are only drawings; each structure alone does not represent an existing molecule. D.) resonance structures all have electron localized structures, while the real species that is described by...
Draw three resonance structures for CNS. This species has its three atoms bonded sequentially in the following fashion: C-N-S. Draw your resonance structures so that the atoms in them are bonded together in this order Select the most important resonance structure for this species based on the formal charges on the atoms of the three resonance structures you have drawn. Select the choices from below which make the statements true about this (most important) resonance structure (a) The leftmost bond...
