Study Notes
Carbon and its Compounds
- Carbon's atomic number is 6, with an electronic configuration of 2,4.
- Carbon cannot readily gain or lose electrons to achieve a stable configuration like inert gases. It needs to share electrons to form covalent bonds.
- A covalent bond forms when atoms share one or more pairs of electrons.
- Covalent bonds commonly form between non-metal atoms.
- Covalent compounds are formed by sharing electrons between atoms.
- Covalent bonds are classified into single, double, and triple bonds based on the number of electron pairs shared.
Types of Covalent Bonds
- Single covalent bond: Forms when two atoms share one pair of electrons. Represented as a single dash (e.g., H-H).
- Double covalent bond: Forms when two atoms share two pairs of electrons. Represented as a double dash (e.g., O=O).
- Triple covalent bond: Forms when two atoms share three pairs of electrons. Represented as a triple dash (e.g., N≡N).
Examples of Covalent Molecules
- Hydrogen (H₂): Two hydrogen atoms share one electron pair, forming a single covalent bond.
- Chlorine (Cl₂): Two chlorine atoms share one electron pair, forming a single covalent bond.
- Sulphur (S₈): Eight sulphur atoms form a ring structure through single covalent bonds.
- Water (H₂O): Two hydrogen atoms and one oxygen atom form single covalent bonds.
- Ammonia (NH₃): One nitrogen atom and three hydrogen atoms form single covalent bonds.
- Methane (CH₄): One carbon atom and four hydrogen atoms form single covalent bonds.
- Oxygen (O₂): Two oxygen atoms share two electron pairs, forming a double covalent bond.
- Carbon Dioxide (CO₂): One carbon atom and two oxygen atoms form double covalent bonds.
- Nitrogen (N₂): Two nitrogen atoms share three electron pairs, forming a triple covalent bond.
Allotropes of Carbon
- Allotropy refers to the different physical forms of an element in the same state.
- Diamond: Each carbon atom is bonded to four other carbon atoms in a rigid three-dimensional structure.
- Graphite: Each carbon atom is bonded to three other carbon atoms, forming a layered hexagonal structure. It is a good conductor of electricity.
- Buckminster Fullerene (C₆₀): Carbon atoms arranged in a spherical or football-like shape.
Difference Between Ionic and Covalent Compounds
- Ionic Compounds: Formed by electron transfer. Generally solid at room temperature and have high melting/boiling points. Often soluble in water and conduct electricity in molten or aqueous states.
- Covalent Compounds: Formed by electron sharing. Can be solid, liquid, or gas at room temperature. Have low melting/boiling points and are often insoluble in water. Do not conduct electricity in molten or aqueous states.
Hydrocarbons
- Hydrocarbons are compounds composed of only carbon and hydrogen.
- They are classified as saturated or unsaturated depending on the types of bonds between the carbon atoms.
- Saturated Hydrocarbons (Alkanes): Have only single bonds between carbon atoms and follow the general formula CₙH₂ₙ₊₂. Alkanes are relatively unreactive.
- Unsaturated Hydrocarbons (Alkenes): Contain a carbon-carbon double bond (C=C), and follow the general formula CₙH₂ₙ.
- Unsaturated Hydrocarbons (Alkynes): Contain a carbon-carbon triple bond (C≡C), and follow the general formula CₙH₂ₙ₋₂.
Naming of Hydrocarbons
- A system for naming hydrocarbons based on the number of carbon atoms is used. Prefixes for the number of carbons are given.
