INORGANIC MADE EASY

1. Remember first and the last element of the group
2. When first & any element of group is compared then exceptional properties are due to anamolous behaviour
3. When last & any element of group is compared then exceptional properties are due to inert pair effect
4. Any compound if fumes in air it is due to formation of HCl
5. Any question related to angle of bond see the position of bonded electrons on the central atom and size of atom if all electrons-bonded & lone pairs are concentrated on atom & size is small so repulsions & angle increases if not angle is less
6. Any compound has different bond length it is due to different types of bonds
7. Any compound is passive towards a reagent only if it forms oxide layer
8. If last element shows exceptioal properties it is due to presence of poor shielding orbitals
9. A compound is more covalent if it has more oxidation state
10. Proticity means number of OH bonds
11. For predicting oxidant or reductant property of any elememt in compound check:

• group of element
• max. & min. oxidation state it can show
• what oxidation state it is showing in given compound & answer
• if max. it will be oxidant :if min. it will be reductant: if intermediate it will be both
