**Title: Evaluating Lewis Structures for Different Molecules** **Instructions:** Decide whether the proposed Lewis structure for each molecule is reasonable or not. **Table of Molecules:** 1. **CO₂** - **Proposed Lewis Structure:** - Displays a carbon atom (C) double-bonded to two oxygen atoms (O). Each oxygen has two lone pairs of electrons. - **Evaluation Options:** - Yes, it's a reasonable structure. - No, the total number of valence electrons is wrong. The correct number is: _______ - No, some atoms have the wrong number of electrons around them. The symbols of the problem atoms are: _______ 2. **IBr₂⁻** - **Proposed Lewis Structure:** - Displays an iodine atom (I) single-bonded to two bromine atoms (Br). Each bromine atom has three lone pairs of electrons, and the entire structure has a negative charge. - **Evaluation Options:** - Yes, it's a reasonable structure. - No, the total number of valence electrons is wrong. The correct number is: _______ - No, some atoms have the wrong number of electrons around them. The symbols of the problem atoms are: _______ 3. **SF₃⁻** - **Proposed Lewis Structure:** - Displays a sulfur atom (S) single-bonded to two fluorine atoms (F) and double-bonded to one fluorine atom. Each fluorine has three lone pairs of electrons, and the entire structure has a negative charge. - **Evaluation Options:** - Yes, it's a reasonable structure. - No, the total number of valence electrons is wrong. The correct number is: _______ - No, some atoms have the wrong number of electrons around them. The symbols of the problem atoms are: _______ **Note:** *If two or more atoms have the wrong number of valence electrons around them, just enter the chemical symbol for the atom as many times as necessary. For example, if two oxygen atoms have the wrong number of electrons around them, enter the symbol O twice.*

**Evaluate the Proposed Lewis Structures for Each Molecule** Below, you will find a table with different molecules, their proposed Lewis structures, and options to assess whether these structures are reasonable or not. | Molecule | Proposed Lewis Structure | Is this a reasonable structure? If not, why not? | |----------|---------------------------|--------------------------------------------------| | CO₂ | ![Proposed Lewis Structure](example) | ⃝ Yes, it's a reasonable structure. <br> ⃝ No, the total number of valence electrons is wrong. <br> The correct number is: [ ] <br> ⬤ No, some atoms have the wrong number of electrons around them. <br> The symbols of the problem atoms are: O | | IBr₂⁻ | ![Proposed Lewis Structure](example) | ⬤ Yes, it's a reasonable structure. <br> ⃝ No, the total number of valence electrons is wrong. <br> The correct number is: [ ] <br> ⃝ No, some atoms have the wrong number of electrons around them. <br> The symbols of the problem atoms are: [ ] | | SF₃⁻ | ![Proposed Lewis Structure](example) | ⃝ Yes, it's a reasonable structure. <br> ⃝ No, the total number of valence electrons is wrong. <br> The correct number is: [ ] <br> ⬤ No, some atoms have the wrong number of electrons around them. <br> The symbols of the problem atoms are: F | **Note:** If you agree that the number of electrons is incorrect, please provide the correct number. This table helps students learn how to analyze Lewis structures by determining if the distribution of electrons follows the octet rule and other valence electron principles.
