Agriculture and Industry - Bonding, structure and properties
7 important questions on Agriculture and Industry - Bonding, structure and properties
What type of particles do covalent network substances have?
Atoms
What type of particles do metallic substances have?
positive ions surrounded by delocalised electrons
What are the typical properties of ionic compounds in terms of Mpt/Bpt, Hardness, Conductivity, Solubility in water, Solibility in non-polar solvents?
Hardness = hard but brittle
Conductivity = conducts in molten or dissolved in water
Solubility in water = often soluble
Solibility in no-polar solvents = generally insoluble
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What are the typical properties of metallic compounds in terms of Mpt/Bpt, Hardness, Conductivity, Solubility in water, Solibility in non-polar solvents?
Hardness = hard but malleable
Conductivity = conduct when solid or liquid
Solubility in water = insoluble
Solibility in no-polar solvents = insoluble
What are the typical properties of simple molecular compounds in terms of Mpt/Bpt, Hardness, Conductivity, Solubility in water, Solibility in non-polar solvents?
Hardness = soft
Conductivity = do not conduct
Solubility in water = usually insoluble, unless molecules contain groups which can hydrogen bond with water
Solibility in no-polar solvents = usually soluble
What type of particles do simple molecular compounds have? What are they held together by?
Small molecules held together by weak intermolecular forces
Explain why many ionic substances are soluble in water, naming the bonds broken and made.
- ionic bonds broken
- ion dipole bonds formed
- hydrogen bonds in water are broken
- similar strength between bonds broken and made
