- Use the principles of resonance theory to explain why carbocation A is more stable than carbocation B.arrow_forwardWhat do equal signs convert to in a condensed formula ? I’m not sure if that’s a double bond. Not sure I expanded correctly and not sure how to convert the first 2 CH3’s into a Lewis without violating octet rule. Thanks for any informationarrow_forwardidentify which is the most and least basic among the given. refer to the number and stability of their resonance structure.arrow_forward
- Label each non-hydrogen atom in the structure below with its formal chargearrow_forwardWhat is the formal charge on each atom indicated in the following structure?arrow_forwardWhich of the given resonance structures (A, B, or C) contributes most tothe resonance hybrid? Which contributes least??arrow_forward
- Explain why this Lewis structure for CO is not as valid as the Lewis structure you drew in theprevious question even though it has no “hot spots” of + or charge (formal charges).arrow_forwardIs bond formation endothermic or exothermic? Write a + or sign above the arrow in the previousquestion to represent the sign of the energy change associated with the arrow.arrow_forwardThe C=O double bond is called a “carbonyl bond.” Acetone and othercarbonyl compounds are introduced in some texts along with this structure a. Is this an important resonance structure of acetone? Explain. b. Does this structure convey any useful information about acetone? If so, what?arrow_forward
- Write Lewis structures for the following: (a) SeF6 (b) XeF4 (c) SeCl3+arrow_forwardIt is impossible to draw a legitimate Lewis structure of a neutral NH4 molecule. Hypothetically,how many valence electrons would such a neutral NH4 molecule have ifit could exist? a. The +1 cation, NH4+ , does exist. How many valence electrons does one NH4+ ion have? b. Draw the Lewis structure for NH4+arrow_forwardExplain how and bonds are similar and how they are different.arrow_forward
