Understanding Sigma Bonds
* Sigma bonds (σ bonds) are the strongest type of covalent bond. They are formed by the direct overlap of atomic orbitals along the internuclear axis.
* Single bonds are always sigma bonds.
Analyzing the Molecule
1. Central Carbon: The carbon atom in CH₂Cl₂ forms four single bonds:
* Two bonds to hydrogen atoms (C-H)
* Two bonds to chlorine atoms (C-Cl)
2. Hydrogen and Chlorine: Each hydrogen and chlorine atom forms one single bond (H-C and Cl-C).
Counting the Sigma Bonds
Therefore, there are a total of 4 sigma bonds in CH₂Cl₂.
