2.3 Structure and bonding of carbon

• Match the type of covalent bond with its description:

  Single bond ↔️ Carbon shares 1 pair of electrons

  Double bond ↔️ Carbon shares 2 pairs of electrons

  Triple bond ↔️ Carbon shares 3 pairs of electrons
• Match the property with the correct allotrope of carbon:

  Diamond ↔️ Giant covalent network

  Graphite ↔️ Layered structure
• Carbon forms covalent bonds by sharing its 4 valence electrons with other atoms.
• The ability of carbon to form single, double, and triple bonds allows it to create a vast range of complex molecules.
• Fullerenes are hollow, spherical or ellipsoidal molecules composed entirely of carbon atoms.
• The flexibility of carbon bonding allows it to build a wide array of organic molecules, crucial for life and industrial applications.
• Carbon is a versatile element known for its ability to form covalent bonds.
• Carbon bonding is crucial because it enables carbon to form three types of bonds: single, double, and triple.
• Graphite conducts electricity due to free electrons between its layers.

  True
• Carbon can form single, double, and triple bonds.


  True
• In graphite, each carbon bonds to 3 others covalently in layers.
• Match the feature of fullerenes with its description and example:

  Structure ↔️ Hollow cage made of carbon atoms, C60

  Shape ↔️ Spherical or ellipsoidal, Buckminsterfullerene

  Bonding ↔️ Covalent bonds between carbon atoms, Single and double bonds
• Carbon achieves a stable electron configuration by sharing its valence electrons.


  True
• Carbon's ability to form different bond types is essential for creating complex molecules.


  True
• Carbon bonding involves covalent bonds where carbon shares its valence electrons.
• Match the bond type with the number of electron pairs shared and an example:

  Single bond ↔️ 1 pair, Ethane (C-C)

  Double bond ↔️ 2 pairs, Ethene (C=C)

  Triple bond ↔️ 3 pairs, Ethyne (C≡C)
• Graphite is very hard due to its layered structure.

  False
• Carbon bonding is essential in organic chemistry because it allows carbon to form strong covalent bonds with itself and other elements.
