Question

State any three points of differences between ionic and covalent compounds

Answer 1

Ionic -good conductors of electricity
Covalent-Bad conductors of electricity
Ionic – soluble in water but insoluble in organic solvents
Covalent – insoluble in water but soluble in organic solvents
Ionic – high melting point
Covalent – low melting point

Answer 2

ionic compounds:

1. bond formed between metallic and non metallic atom
2. formed by  transfer of electrons from metal atom to non metallic atom
3. eg.NaCl

covalent compounds:

1. bond formed between non metallic atoms
2. formed by mutual sharing of electrons between pair of atoms
3. eg.N₂
