  • Covalent Compounds & Separation
    • Covalent Bonds
      • Substances with CB may be simple or have giant molecular structures
      • Simple Covalent substances have low melting point and dont conduct electricity
      • Pairs of electrons shared in covalent bonds
      • Dot and x diagrams used
      • Giant structures like lead / diamond have covalent bonds
      • The type of bonding present determines properties of substance
    • Separation techniques
      • Miscible liquids can be separated using fractional distillation
      • Immicible liquids can be seperated using seperating funnel
      • chroma-tography seperates coloured componds in mixture
