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.
![**Lewis Structure Analysis for Bond Angle, Hybridization, and Molecular Shape**
This educational page provides instructions for analyzing a given Lewis structure of a molecular compound. The aim is to determine the bond angles, hybridization, and molecular shape of specific atoms that are indicated with arrows.
**Instructions:**
1. **Identify the Bond Angle:** Assess the geometry around the atom in question and estimate the bond angle. Use “<” or “=” signs as appropriate. Common bond angles to consider are:
- 180° for linear geometry
- 120° for trigonal planar
- 109.5° for tetrahedral
- Less than 109.5° for bent or trigonal pyramidal
2. **Determine the Hybridization:** Look at the bonding and lone pairs around the atom to identify the hybridization. Possible hybridizations include:
- sp for linear
- sp² for trigonal planar
- sp³ for tetrahedral
3. **Identify the Molecular Shape:** Based on the bonding pairs and lone pairs, determine the molecular shape using VSEPR theory. Shapes include:
- Linear
- Bent
- Trigonal planar
- Tetrahedral
- Trigonal pyramidal
