(a)
Interpretation:
TInterpretation: The shape of the indicated N and O atom in the molecule needs to be determined.
Concept Introduction:
The geometry around any atom depends on the number of bond pairs and lone pairs of electrons around it. There are approximate bond angles between atoms, defined for a particular geometry as follows:
Molecular geometry around interested atom | Bond angle (') |
Linear | 180 |
Trigonal planer | 120 |
Tetrahedral | 109.5 |
Trigonal pyramidal | 109.5 |
Bent | 109.5 |
(b)
Interpretation:

- How do you know when to draw a solid wedge vs a dashed wedge when drawing 3D bond-line structures? I know that solid-wedge means the atom is pointing towards you and dashed wedge means it's in the back, but how do you know which atoms are in the front as opposed to the back? How can you tell what the configuration will look like in space just by looking at the lewis structure or name?arrow_forwardWrite a Lewis structure for each of the following molecules. H3COCH3 (oxygen is between the two carbon atoms) Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.arrow_forwardWrite a Lewis structure for each of the following molecules. H3COH (carbon and oxygen are both central) Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.arrow_forward
- Part ADraw the Lewis structure for HCCH (ethyne).Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all hydrogen atoms and all lone pairs of electrons. Part BDraw the Lewis structure for CS2 (where C is the central atom).Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.arrow_forwardComplete the following Lewis structure by adding in missing lone pairs and pi bonds. Assume all atoms are neutral (having no formal charge). Do not add additional atoms to the structure.arrow_forwardDraw two resonance structures of the given molecule/ion. Be sure to include all lone pairs. :Ö:arrow_forward
- Distribute the electrons among the atoms, giving octets (or duets for hydrogen) to as many atoms as possible. Begin with the bonding electrons, and then proceed to lone pairs on terminal atoms, and finally to lone pairs on the central atom.arrow_forwardPick the approximate bond angle indicated of the molecule with the Lewis structure below. All atoms except H have an octet of electrons. Lone pairs are not indicated. H C-H H-C-0-C Harrow_forwarddiagram of a molecule that shows atoms based on their a periodic table symbols. These symbols are surrounded by pairs of dots to show valence electrons that could be lone pairs or bonding pairs?arrow_forward
- Write Lewis structures for each of the following species. Use expanded octets as necessary. Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. SF4arrow_forwardDecide whether these proposed Lewis structures are reasonable. proposed Lewis structure 0= --H H-H-O-H H-C-C-H Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* 0 * If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "O,0".
