Study Notes
Differences Between Organic and Inorganic Compounds
- Organic compounds are primarily composed of carbon and elements like hydrogen, oxygen, nitrogen, sulfur, phosphorus, and halogens.
- Inorganic compounds contain a broader variety of elements including metals and non-metals.
- Organic compounds typically consist of covalent bonds, whereas inorganic compounds predominantly feature ionic bonds.
- Organic compounds can exist as gases, liquids, or solids generally with low melting points; inorganic compounds are mostly solids with high melting points.
- Organic compounds are usually insoluble in water but soluble in non-polar solvents, while inorganic compounds tend to be soluble in water and insoluble in non-polar solvents.
- When dissolved in water, organic solutions do not conduct electricity; inorganic aqueous solutions conduct electricity.
- Organic compounds are combustible, producing carbon (soot) when burned; most inorganic compounds are non-combustible and do not yield carbon upon combustion.
- Chemical reactions involving organic compounds are generally slow, while those in inorganic compounds tend to be fast.
Important Properties of Carbon
- Carbon exhibits tetravalency, allowing it to form four strong covalent bonds.
- Capable of forming multiple bonds, including double and triple bonds.
- Carbon can catenate, creating long linear chains, branched structures, and ring formations.
- Carbon atoms in organic compounds are categorized based on their degree of substitution: primary (1°), secondary (2°), tertiary (3°), and quaternary (4°).
Structural Formulas of Organic Compounds
- Correct structural formulas are critical for accurately representing organic compounds and their functional groups.
Functional Groups in Organic Compounds
- Hydrocarbons are the simplest class, comprising only carbon and hydrogen.
Types of Hydrocarbons
- Alkanes: Saturated hydrocarbons with single bonds; names typically end in "-ane."
- Alkenes: Unsaturated hydrocarbons containing at least one carbon-carbon double bond; names typically end in "-ene."
- Alkynes: Unsaturated hydrocarbons with at least one carbon-carbon triple bond; names typically end in "-yne."
- Arenes: Aromatic hydrocarbons featuring a benzene ring; compounds containing these rings are known as aromatic hydrocarbons.
Chemical Bonds
- Atoms bond to achieve stability, primarily involving valence electrons.
- The octet rule states that stability is achieved when an atom has eight electrons in its valence shell.
Ionic Bonds
- Ionic bonds result from the electrostatic attraction between ions, where metals donate electrons to non-metals.
- Characteristics include high melting points and the ability to dissociate into ions in water.
Covalent Bonds
- Covalent bonds form when non-metal electrons are shared, resulting in various states (gases, liquids, solids) and generally low melting points.
- Many covalent compounds are pliable, such as plastics.
Evolution of Organic Chemistry
- Early chemists believed in the Vitalism Theory, asserting only living organisms could synthesize organic compounds.
- This notion was challenged when Friedrich Wohler synthesized urea in 1828 using inorganic precursors.
Organic Chemistry Today
- Organic chemistry studies compounds primarily containing carbon along with elements such as H, O, N, S, P, and halogens.
Hydrocarbon Derivatives
- Hydrocarbon derivatives contain elements other than carbon and hydrogen, introducing functional groups that determine their reactivity.
- Alkyl groups (denoted as "R") are parts of compounds excluding the functional group.
Common Hydrocarbon Derivatives
- Alkyl Halides: Halogen replaces a hydrogen atom; generic formula R-X.
- Alcohols: Contain hydroxyl group (-OH); generic formula R-OH.
- Thiols: Contain sulfhydryl group (-SH); generic formula R-SH.
- Ethers: Contain an oxygen atom between alkyl groups or phenyl rings; generic formula R-O-R'.
- Amines: Contain amino group (-NH); used in pharmaceuticals, insecticides, and various chemicals.
