- 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
