Study Notes
Allotropes of Carbon
- Three well-known allotropes: diamond, graphite, and fullerene.
- Graphite is a good conductor of electricity due to its delocalized electrons.
Structure and Properties
- In graphite, each carbon atom is bonded to three other carbon atoms in a planar structure, forming layers.
- Diamond’s hardness is attributed to its rigid three-dimensional tetrahedral structure, where each carbon atom is bonded to four others.
- Carbon's unique property of forming chains and rings by self-linkage is known as catenation.
Earth and Carbon
- Approximately 0.02% of the Earth's crust is composed of carbon.
- Synthetic diamonds are formed through high-pressure high-temperature (HPHT) methods or chemical vapor deposition (CVD).
Chemical Compounds and Hydrocarbons
- General formula for saturated hydrocarbons: CnH2n+2.
- Compounds formed by the reaction of castor oil with sodium hydroxide are called soaps.
- Compounds with at least one aromatic ring are categorized as aromatic compounds.
- Class of compounds with single, double, or triple bonds between carbon atoms are called unsaturated hydrocarbons.
- Alkynes, a type of unsaturated hydrocarbons, have the general formula CnH2n-2.
Unique Properties and Configurations
- The electronic configuration of carbon is 1s² 2s² 2p².
- The tendency of carbon to form various structures like straight chains, branched chains, or rings is called tetravalency.
- Diamond's unique property is its exceptional hardness, contrasted with graphite's lubricating layers.
Miscellaneous
- Compounds that cannot form lather in hard water are typically soap-related compounds.
- An element exhibiting different physical properties but similar chemical properties in various forms is termed an allotrope.
- The specific allotrope with layers of hexagonal arrays bonded in planes is graphite.
