General Chemistry Tutorials - Grade 11, 12 Advanced Level

General chemistry gives us a basic understanding about chemistry before we start to learn advanced lessons of chemistry. General chemistry includes following sections to cover. These sections may vary according to your country or syllabus. Therefore check your syllabus when you refer this lessons.

  • Structure of atom - Different structures of atoms are explained.
  • Periodic table and its groups, periods, elements and different blocks
  • Electronegativity
  • Chemical bonds - covalent, ionic
  • Different molecular shapes and deciding shapes

Good understanding of general chemistry helps to understand inorganic, organic and physical chemistry very well.

General Chemistry Lessons

Lewis structures and resonance structures

Study following lessons to draw lewis structures and resonance structures.

Lewis structure of NO2- ion (nitrite ion) Lewis structure of NO2 molecule (nitrogen dioxide) How to draw resonance structures Lewis structure and resonance structures of N2O molecule (nitrous oxide) Lewis structure and resonance structures of N2O5 molecule (dinitrogen pentoxide)

Properties of periodic table

Metal characteristics variations Melting,boiling points variation Concentration calculation example Solubility of hydroxides Oxidizing reducing characteristics Oxidation numbers shown of elements

Why you should have a better understanding of general chemistry?

General chemistry covers all the basic theories you want to understand inorganic chemistry, physical chemistry and organic chemistry in grade 11 and 12.

Importance of general chemistry is explained below.

Balancing a chemical redox reaction.

How to balance NaOH and chlorine gas reaction under two conditions, hot concentrated and cold dilute. This reaction meets in p block chemistry under inorganic chemistry. But balancing a redox reaction is taught at general chemistry section.

Intermolecular forces to decide and compare melting and boiling points of organic compounds

Different types of intermolecular forces such as hydrogen bonds, dipole diole forces, vandetvl's forces are learnt in general chemistry. These forces have a very strong effect on melting and boiling points of compounds or elements. We have a long lesson for compare melting and boiling points of organic compounds
