PHYSICAL SCIENCE CORE KNOWLEDGE: MATTER AND MATERIALS offspring: thorough CHEMISTRY CLASS NOTES ____________________________________________________________ _____________ 1. ORGANIC MOLECULES Organic interpersonal chemistry is the of compounds of CARBON excluding CO2, CO, carbonates (CO3) and cyanides (CN-). thither ar millions of these compounds and they range in size of it from simple molecules with 5 atoms to complex structures with thousands of atoms. Although the of the essence(p) element is carbon, new(prenominal)(a) elements much(prenominal) as hydrogen (H), oxygen(O), nitrogen(N), sulphur(S) and phosphorus(P) are also communal in these molecules. 2. SOURCES OF CARBON The main source of carbon in organic compounds is carbon dioxide (CO2) in the air. Plants use sunlight to deepen carbon dioxide into organic compounds through with(predicate) the process of photosynthesis. 6CO2 + 6H2O ? C6H12O6 + 6O2?H > 0 Carbon is also demonstr ate rude(a)ly in fossil fuels such as coal, oil and natural gas. Organic compounds are important are important in our daily life. They draw up a large of each living organisms and are found in the food we eat. They are also used to make products such as the attire we wear, medicines, plastics, washing powders, dyes and many former(a) items. 3.

UNIQUE PROPERTIES OF CARBON Carbon has a few curious properties which are responsible for its behaviour how it reacts and corpse connects. Carbon has 4 valence electrons and they are all accessible for bonding. It forms strong covalent carbon-to-carbon bon ds and allows long chains to form. The chain! s freighter either be straight/un branching (fig. 2) or branched (fig. 3). This property is called catenation. Because of its eyeshot in the periodic table, carbon forms preponderantly covalent bonds with other compounds. The C C bonds are rigorously covalent (non-polar) because the remainder in the electronegativity of the carbon (2.5 2.5) atoms is zero. The C H bond is also non-polar because the difference (2.5 2.1) is very low. The way out of...If you pauperization to get a full essay, order it on our website: OrderCustomPaper.com
