Structural formulas are used to display covalently bonded molecules in the order they are bonded. The atoms may bond using single, double, or triple bonds. Some structural formulas show only the atoms without displaying the complete structure with bond angles and, in some cases, even the bonds.
The different spatial arrangements organic molecules adopt due to the rotation of the single bond are called conformations. A specific conformation is called a conformer or conformational isomer.
Many such conformational isomers are undoubtedly interconvertible by single bond rotations. So, these isomers are simply different rotational (or structural) arrangements of the same molecule.
Electronegativity measures on a scale of 0.8 – 4 an atom’s or group of atoms’ tendency to attract the bond electron pair towards itself, thereby creating partial negative (δ-) and positive (δ+) terminals.
Learning Objective: To learn about the components of an atom and the importance of proton numbers.
Skill Level – Intermediate
Prerequisites:
Learning Objective: To study the various examples of organic reactions where the leaving group departs from a molecule and also understand its various types.
Prerequisites:
Displacement and Elimination type of reaction (Chapter- Common Types of Reactions)
Ionic Bond | Covalent Bond | Metallic Bond | Van der Waal Forces |
|---|---|---|---|
Ionic bonds form due to the complete transfer of electrons. | Covalent bonds form due to sharing of electrons. | Metallic Bond forms between a Metal (cation) and delocalized electrons. |
