STPM Chemistry Form 6 Note – Introduction of Organic Chemistry

by BerryBerryTeacher

in Berry Reference (Notes)

Organic chemistry is the study of carbon-based compounds (with emphasise on hydrocarbon for STPM Chemistry/Form 6 Malaysia) in terms of strutural properties, its composition and their involved reactions. The compounds that are deemed to be organic compounds are wide-ranging. Carbon compounds (with the exception of some inorganic carbon compounds) are usually organic in nature. At the moment, there are over six million organic compounds catalogues in databases. This note from Berry Berry Easy on the Introduction of Organic Chemistry for Form 6 STPM Chemistry will give Berry Readers an introduction on hydrocarbons.

As for hydrocarbons, as most students would already have learnt in SPM Chemistry, they are organic compounds which contain only Carbon (C) and Hydrogen (H) atoms. Among example of hydrocarbon classes are alkanes, alkenes, alkynes and aromatic hydrocarbons. They are typically insoluble in water and is good fuel material. The different in classes are due to the presence of double and triple bonds in its structure. More on the specific hydrocarbon classes will be presented in the other notes in the related series. Do read on and get acquaintant with the berry berry important grand section of organic chemistry for STPM Chemistry.

[Tips: While most carbon compounds are organic, exceptions include inorganic compounds such as the bicarbonates of metal ions, carbonate of ions, oxides of carbons, metal cyanide and others. Students also often forget why HCs are insoluble in water. The insolubility of hydrocarbons stemmed from its relative non-polarity.]

Covalent Bond

Covalent Bond


  • Hydrocarbon whose carbon- carbon bonds are all single covalent bonds
  • Major sources: Petroleum and coal (decay and degradation of marine plants and animals)
  • Examples: methane (natural gas), propane / butane ( bottled fuel gas – camping equipment)
  • Hydrocarbons in petroleum are burned as fuel and small portion is converted into petrochemicals (plastics, dyes, detergents, pesticides etc.)

We have reach the end of the Introduction to Organic Chemistry. Easy? Yes. But the difficult part is about to come soon. Do stay tune for notes on alkane, alkene and other hydrocarbons (and also other organic compounds).
