Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent.
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
Question
Transcribed Image Text:**Title: Evaluating Lewis Structures for Molecular Accuracy**
**Objective:**
Determine whether the proposed Lewis structures for each molecule are reasonable. If not, identify the issues in terms of electron count or distribution.
**Molecules and Their Proposed Lewis Structures:**
1. **\( \text{NH}_2^+ \)**
- Structure: Involves nitrogen (N) bonded to two hydrogen atoms (H), with a positive charge.
- Options for Evaluation:
- Yes, it's a reasonable structure.
- No, the total number of valence electrons is wrong. (Indicate the correct number)
- No, some atoms have the wrong number of electrons around them. (List problematic atoms)
2. **\( \text{O}_3 \)**
- Structure: Linear arrangement with alternating single and double bonds between three oxygen atoms (O).
- Options for Evaluation:
- Yes, it's a reasonable structure.
- No, the total number of valence electrons is wrong. (Indicate the correct number)
- No, some atoms have the wrong number of electrons around them. (List problematic atoms)
3. **\( \text{IBr}_2^- \)**
- Structure: Iodine (I) centrally bonded to two bromine atoms (Br), with an overall negative charge.
- Options for Evaluation:
- Yes, it's a reasonable structure.
- No, the total number of valence electrons is wrong. (Indicate the correct number)
- No, some atoms have the wrong number of electrons around them. (List problematic atoms)
**Instructions:**
- If two or more atoms have the incorrect number of valence electrons, list the symbol for the atom the appropriate number of times.
**Note:**
Analyze each structure by comparing to known valence electron configurations and molecular stability principles. Use this understanding to critically assess the validity of the proposed Lewis structures.
