Study Notes
Bonding in Carbon Compounds
- The electronic configuration of carbon that allows it to form 4 bonds in a compound is 1s² 2s² 2p².
- Carbon typically forms covalent bonds in its compounds.
Addition Reaction
- When chlorine is added to methane (CH₄) in the presence of sunlight, the likely product is chloromethane (CH₃Cl).
Hybridization in Carbon
- When carbon forms 3 sigma bonds and no lone pairs, its hybridization state is sp³.
Classification of Compounds
- CH₃Cl + HCl is classified as an organic compound.
Oxidation Reaction
- In the reaction involving ethanol, potassium dichromate, and sulfuric acid, potassium dichromate acts as an oxidizing agent.
Nomenclature of Carbon Compounds
- The characteristic that determines whether a carbon compound is named as an alkane, alkene, or alkyne is the presence of single, double, or triple bonds between carbon atoms.
Soap Molecules
- A soap molecule has one end that is ionic due to the presence of a negatively charged carboxyl group (-COO⁻) and a positively charged sodium ion (Na⁺).
Substitution Reaction
- When chlorine gas is added to a hydrocarbon in sunlight, chlorine substitutes hydrogen atoms due to the formation of a more stable chlorine-carbon bond.
