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 coat from simple molecules with 5 atoms to complex structures with thousands of atoms. Although the big element is carbon, different elements such as hydrogen (H), oxygen(O), nitrogen(N), sulphur(S) and phosphorus(P) are also common land 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 transform carbon dioxide into organic compounds through with(predicate) the process of photosynthesis. 6CO2 + 6H2O ? C6H12O6 + 6O2?H > 0 Carbon is also tack together rude(a)ly in fossil fuels such as coal, oil and natural gas. Organic compounds are important are important in our daily life. They shed 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 some otherwise items. 3.

UNIQUE PROPERTIES OF CARBON Carbon has a few rummy properties which are responsible for its behaviour how it reacts and corpse link ups. Carbon has quaternion valence electrons and they are all accessible for bonding. It forms strong covalent carbon-to-carbon bonds and allows long chains to form. The chains freighter either be straight/un branching (fig. 2) o r branched (fig. 3). This property is called! catenation. Because of its spatial relation in the periodic table, carbon forms preponderantly covalent bonds with other compounds. The C C bonds are rigorously covalent (non-polar) because the dissimilitude 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 lack to get a full essay, order it on our website: OrderEssay.net
