Study Notes
Condensation Reactions
- Condensation reactions are observed in biological processes, like protein production.
- Two or more molecules combine, releasing a water molecule.
- This is an important aspect of biological systems.
Preparing Aldehydes
- These steps are involved in producing aldehydes:
- Oxidation of alcohols
- Oxidation of aldehydes
Nucleic Acids
- Nucleic acids are crucial biomolecules.
- They transmit and express information within and outside the cell nucleus.
- DNA and RNA are examples of nucleic acids.
- Nucleic acid sequence carries encoded information.
Aldehydes and Ketones Similarities
- Aldehydes and ketones are both polar.
- They contain carbon-oxygen double bonds.
- A hydrocarbon group is attached to the carbonyl carbon.
- They have higher boiling and melting points than alkanes.
Esters
- Esters have the general formula R'-COOR.
- They are used for perfumes and flavorings.
- Esters contain a carbonyl group (C=O)
- R', R are hydrocarbon chains.
Structural Isomerism
- Structural isomers have the same molecular formula, but different structures and properties.
- They are different variations of the same molecules.
Addition Reactions
- Addition reactions involve adding atoms or groups of atoms to double or triple bonds in hydrocarbons.
- Reactants (A and B) are added across the broken double or triple bond.
Polyesters
- Polyester formation involves dicarboxylic acids and dialcohols.
Polymer Classification
- Polymers are classified based on source and structure, not cost or functionality.
Ethers
- Ethers have the R-O-R' linkage.
- R and R' are hydrocarbon groups.
- Ethers are polar, but they are slightly soluble in water.
- Ethers are flammable compounds.
Branched Chain Polymers
- Branching in polymers leads to:
- Lower density
- Lower melting points
- Lower thermal conductivity
Linear Polymers
- Linear polymers have a straight chain structure.
- The arrangement of side groups affects the properties.
- Monomers link up to form a backbone, which is a chain.
Functional Group Isomerism
- Functional group isomers have different functional groups and different properties, despite having the same molecular formula.
- Examples include Propanal and Propanone, Ethanol and Dimethyl ether, 1,1-dichloroethane and 1,2-dichloroethane, Propanoic acid and Ethyl methanoate.
Disaccharides and Monosaccharides Similarities
- Both are formed by linking monosaccharides together through condensation reactions.
Lipid Structure
- Lipids have fatty acid chains with carbon atoms.
- Saturated lipids have single bonds between carbons, usually solid at room temperature.
- Unsaturated lipids have double bonds between carbons, usually liquid at room temperature.
Preparing Organic Compounds
- Organic compounds are prepared through synthesis.
- Laboratory techniques and various chemical reactions might be involved.
Carboxyl Functional Group
- A carboxyl group has a carbon double-bonded to an oxygen and a hydroxyl group (OH) bonded to the same carbon.
Cross-linked Polymers
- Cross-linked polymers form three-dimensional networks.
- Cross-linked polymers are hard and brittle.
Protein Function
- Proteins support connective tissues, facilitate biochemical reactions, serve as messenger proteins to coordinate body functions, and store amino acids.
- Proteins are essential in muscle contraction.
