Properties of compounds and molecule 0.0 / 5 ? ChemistryBonding & shapesASOCR Created by: Pheebzicles01Created on: 30-05-18 10:05 Solubility of ionic molecule Depends on the strength of charges 1 of 19 2 stages of solubility lattice broken down & ions surrounded 2 of 19 Boiling point of ionic compounds High - needs high amounts of energy to overcome electrostatic forces 3 of 19 Ionic compounds conductivity Conducts when molten not solid 4 of 19 Why can ionic compounds conduct when molten? Ions are mobile so can carry the charge 5 of 19 Boiling point of metallic lattice High - strong electrostatic forces in all directions from cation to delocalised electrons 6 of 19 Conductivity of metallic lattices Conducts - delocalised electrons able to move 7 of 19 Solubility of metallic lattices Insoluble - interactions lead to reactions 8 of 19 Simple covalent boiling point Low 9 of 19 Simple covalent BP reason Only weak intermolecular forces to overcome 10 of 19 Conductivity of simple covalent molecules Doesn't conduct 11 of 19 Solubility of non-polar covalent compound in non-polar solvents Dissolves 12 of 19 Polar covalent compounds solubility Depends on the strength of the dipole 13 of 19 Non-polar compounds in polar solvents solubility Solvents bonds are too strong to overcome 14 of 19 Giant covalent lattice boiling point High 15 of 19 Reason for high boiling point of giant lattice Covalent bonds have to be broken 16 of 19 Conductivity of giant covalent Doesn't apart from graphene or graphite 17 of 19 Explain graphene's conductive properties Graphene has a delocalised electron for every atom which is mobile to carry charge. This is because carbon only attaches to 3 other carbons 18 of 19 Solubility of giant covalent insoluble - covalent bonds are too strong to break 19 of 19
