Study Notes
Covalent Bonding
- The simplest molecule formed by sharing valence electrons is hydrogen (H2), where two hydrogen atoms share their electrons to attain the electronic configuration of the nearest noble gas, helium.
- A single covalent bond is represented by a line between the two atoms.
Electronic Configuration of Chlorine and Oxygen
- Chlorine has an atomic number of 17, and its electronic configuration is not specified in the text.
- Oxygen forms a double bond between two oxygen atoms.
Properties of Carbon
- Carbon has the unique ability to form bonds with other atoms of carbon, giving rise to large molecules, a property called catenation.
- Carbon can form chains, branched chains, or rings, and may be linked by single, double, or triple bonds.
- Compounds of carbon with single bonds between carbon atoms are called saturated compounds, while those with double or triple bonds are called unsaturated compounds.
- The carbon-carbon bond is very strong and hence stable.
Substitution Reaction
- Saturated hydrocarbons are fairly unreactive and are inert in the presence of most reagents.
- Chlorine can replace the hydrogen atoms one by one in a substitution reaction, which occurs in the presence of sunlight.
Ethanol and Ethanoic Acid
- Ethanol is a liquid at room temperature, commonly called alcohol, and is the active ingredient of all alcoholic drinks.
- Ethanol is a good solvent and is used in medicines such as tincture iodine, cough syrups, and many tonics.
- Ethanol is soluble in water in all proportions.
Electronic Configuration of Carbon
- The atomic number of carbon is 6, and its electronic configuration is not specified in the text.
- Carbon has four electrons in its outermost shell and needs to gain or lose four electrons to attain noble gas configuration.
