Study Notes
Coordinate Covalent Bonding
- Coordinate covalent bonds and covalent bonds both involve the sharing of electron pairs.
- The major difference lies in electron contribution: coordinate covalent bonds involve two electrons from a single atom, while covalent bonds involve electron pairs from two different atoms.
Energy Levels
- Electron capacity for each energy level:
- 1st level: 2 electrons
- 2nd level: 8 electrons
- 3rd level: 18 electrons
- 4th level: 32 electrons
Charge of Ions
- Ammonium carries a positive charge (+1) due to accepting a proton from chloride.
- Chloride gains a negative charge (-1) as it retains more electrons than protons after losing a hydrogen atom.
Structural Representation
- In coordinate bonds, an arrow in structural diagrams indicates the direction of electron donation towards the atom that does not contribute electrons.
Independent Hydrogen Atom
- An independent hydrogen atom consists solely of a proton and is highly reactive, making its isolation impractical.
Water Molecule Representation
- The notation "aq" denotes that an ion is associated with a water molecule, indicating its aqueous state.
Sublimation
- Sublimation is the process where a substance transitions directly from a solid state to a gas, bypassing the liquid phase.
Covalent Nature of Sublimation
- If a substance sublimes at low temperatures, it suggests that the compound is covalent in nature due to weaker intermolecular forces.
Dimer Definition
- A dimer is formed when two molecules connect through a coordinate covalent bond.
Stability and Energy
- Formation of a coordinate bond releases energy, resulting in greater stability for the dimer formed.
Diagrammatic Representation
- In simple diagrams, coordinate covalent bonds are represented by an arrow pointing from the donor atom to the acceptor atom.
Arrow Directionality
- The arrow in coordinate bond diagrams points to the atom that is accepting the electron pairs, indicating its role in the bond formation.
