Study Notes
Identifying Organic Compounds
- Organic compounds contain carbon and hydrogen, and may also contain oxygen, nitrogen, halogen and sulfur.
- They are typically covalently bonded.
- Organic compounds usually come from living things.
Differences Between Organic and Inorganic Compounds
- Definition: Organic compounds are derivatives of hydrocarbons, while inorganic compounds are derived from elements.
- Source: Organic compounds are commonly found in living organisms, sometimes in non-living things. Inorganic compounds originate from non-living sources.
- Composition: Organic compounds primarily contain carbon and hydrogen, sometimes with other elements. Inorganic compounds can contain various elements.
- Solubility: Organic compounds are generally soluble in non-polar solvents, while inorganic compounds are often soluble in water.
- Chemical bonding: Organic compounds usually exhibit covalent bonding. Inorganic compounds typically have ionic bonding.
- Melting point: Organic compounds have low melting points, while inorganic compounds have high melting points,
- Boiling point: Organic compounds have low boiling points. Inorganic compounds have high boiling points.
- Catenation: Organic compounds form long chains easily, a process called catenation. This is rarely seen in inorganic compounds.
- Isomerism: Isomers are possible in organic compounds, this is not the case with inorganic compounds.
- Stability: Organic compounds often break down (decompose) easily when heated. Inorganic compounds generally do not decompose when heated.
- Flammability: Organic compounds tend to be flammable, while inorganic compounds usually are not.
- Conductivity: Organic compounds are non-electrolytes, unlike inorganic compounds, which are typically electrolytes.
- Rate of reactions: Organic reactions tend to be slower than inorganic reactions.
Procedure for Identifying Organic Compounds
- Preliminary investigation: This includes observing physical properties such as color, state (solid, liquid), odor.
- Detection of elements: Tests for the presence of elements like halogen, nitrogen and sulfur.
- Allocation of class: This commonly involves solubility tests.
- Confirmation of functional groups: Tests to identify specific functional groups.
- Melting/boiling point determination: Determining melting and/or boiling points.
- Confirmatory tests: These tests confirm the specific compound.
Physical Properties of Organic Compounds—Step 1
- Physical state: Organic compounds can exist as solids (crystalline or amorphous), liquids (viscous or non-viscous).
- Color: Many organic compounds have specific colors due to chromophoric groups or impurities.
Detection of Elements in Organic Compounds—Step 2
- Lassaigne's solution: This solution is necessary for detecting nitrogen, sulfur and halogens.
- Mechanism: The solution is made by fusing an organic compound with sodium and then dissolving the resulting product in water.
Qualitative Tests for Elements in Organic Compounds—Step 2.2
- Nitrogen: Ferrous sulphate test (identifies nitrogen using characteristic Prussian blue color.)
- Sulphur: Sodium nitroprusside test (violet color indicates the presence of sulfur).
- Halogens: Silver nitrate test (formation of specific precipitates indicate presence of chlorine, bromine or iodine.)
Allocation of Organic Compounds—Step 3
- Compounds can be categorized by their solubility in varying liquids to assess their properties.
- Types of Compounds: Acidic, Basic, Neutral, Inert.
Determination of Functional Groups—Step 4
- Tests confirm the specific functional groups of organic compounds.
Confirmatory Tests for Compounds—Step 6
- Detailed tests confirm the identification of the specific compound.
