- The oxygen atom in acetone possesses ____ unshared pairs and ____ shared pairs of electrons. The number of electrons that belong to oxygen is ____. Oxygen is a Group ____ element. The formal charge on oxygen in acetone is ____.arrow_forwardWhich elements on the periodic table (other than H) are likely to form a+1 cation?arrow_forwardThe Lewis structure of acetone is Circling the carbonyl carbon, i.e., the carbon atom attached to oxygen, and its octet gives Circling the oxygen atom and its octet gives Thus, atoms share electrons in making bonds, and a pair of electrons may be included in the octet of two different atoms. When computing the formal charge on an atom, the number of electrons that belong to that atom is compared with the number of electrons the atom would have in the unbonded and neutral state. If the two numbers are the same, the formal charge on the atom is zero. In a Lewis structure both electrons in an unshared pair belong to the atom, and one of every pair of shared (bonding) electrons belongs to the atom.arrow_forward
- Ethanol, , is a compound in which the formal charge on all the atoms is zero. Under certain conditions the bond can be broken so that both electrons remain with the oxygen atom. The products are In this structure the oxygen owns one electron from shared pair and two electrons from each of unshared pairs. The total number of electrons belonging to oxygen is Oxygen is a Group element. The formal charge on the oxygen atom is . The correct Lewis structure for the ethoxide ion is Note that the other fragment, the proton, leaves with a formal charge of +1.arrow_forwardDraw two curved arrows to give a stable resonance structure that fulfills the octet rule.arrow_forwardQuestion: Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons and any nonzero formal charges.arrow_forward
- Two major resonance structures are possible for the anion shown. One resonance form is given, but it is incomplete. Complete the given structure by adding nonbonding electrons and formal charges. Draw the remaining structure, including nonbonding electrons and formal charges. Omit curved arrows. Structure A: complete the structure by adding nonbonding electrons and formal charges. H H H I Structure B: draw the remaining resonance structure, including nonbonding electrons and formal charges. H- : z: H Harrow_forwardConsider the following two resonance structures: Does the arrow pushing pattern represents the flow of electrons that converts the first resonance structure into the second resonance structure? And if not draw the correct bond line structure.arrow_forwardProvide all reasonable resonance structures using curved arrows to show the movement of electrons. If no reasonable resonance structures can be drawn, specify “No Resonance Structures”.arrow_forward
- 1. Draw the resonance structures of the following molecule, using curved arrows to show electron movement and appropriate arrows to show the relationship between the structures. All lone pairs and charges must be clearly shown.arrow_forwardDraw the Lewis structure created by the curved arrow. Write in formal charges wherever they are not equal to zero. H- EC-H Click and drag to start drawing a structure.arrow_forwardThe complete structural formula is the expanded formula explicitly showing every atom and every bond.arrow_forward
