p-Block Group 14 Elements: The Carbon Family — Syllabus & Topics

Topics covered in p-Block Group 14 Elements: The Carbon Family for JEE Mains Chemistry.

Topics in p-Block Group 14 Elements: The Carbon Family

1

General Characteristics and Periodic Trends

  • Electronic configuration: ns²np² where n = 2 to 6
  • Metallic character: C (non-metal) → Si (metalloid) → Ge (metalloid) → Sn, Pb (metals)
  • Covalent radii order: C < Si < Ge < Sn < Pb
2

Allotropes of Carbon

  • Diamond: sp³ hybridized, tetrahedral structure, hardest substance, electrical insulator
  • Graphite: sp² hybridized, layered structure with π-electrons, conducts electricity
  • Fullerenes: C₆₀ (12 pentagons + 20 hexagons), C₇₀ (12 pentagons + 25 hexagons)
3

Oxides of Group 14 Elements

  • Monoxides (MO): CO (neutral), SiO (high temp only), GeO, SnO, PbO (amphoteric)
  • Dioxides (MO₂): CO₂ (acidic), SiO₂ (weakly acidic), GeO₂, SnO₂ (amphoteric), PbO₂ (basic)
  • Acidic character decreases: CO₂ > SiO₂ > GeO₂ > SnO₂ > PbO₂
4

Hydrides and Halides

  • Hydrides: CH₄ (most stable) > SiH₄ > GeH₄ > SnH₄ > PbH₄ (thermal stability decreases)
  • Reducing character of hydrides increases down the group
  • Tetrahalides (MX₄): All elements form except PbBr₄ and PbI₄ (don't exist)

Key Concepts
