Alkenes Quiz

Definition: Alkenes are unsaturated hydrocarbons that contain one or more carbon-carbon double bonds.
General formula: CnH2n (n = number of carbon atoms)
Nomenclature: Alkenes are named using the suffix "-ene" and the prefix indicating the number of carbon atoms.
Properties:
- Low boiling points and melting points
- Insoluble in water, but soluble in organic solvents
- Can exhibit geometric isomerism (cis-trans isomerism)
Reactions:
- Electrophilic addition reactions (e.g., hydrogenation, halogenation)
- Polymerization reactions

Definition: Alkynes are unsaturated hydrocarbons that contain one or more carbon-carbon triple bonds.
General formula: CnH2n-2 (n = number of carbon atoms)
Nomenclature: Alkynes are named using the suffix "-yne" and the prefix indicating the number of carbon atoms.
Properties:
- Higher boiling points and melting points compared to alkenes
- Insoluble in water, but soluble in organic solvents
- Can exhibit acidity due to the high electronegativity of the triple bond
Reactions:
- Electrophilic addition reactions (e.g., hydrogenation, halogenation)
- Nucleophilic addition reactions (e.g., with water, ammonia)

Definition: Alcohols are organic compounds that contain a hydroxyl (-OH) functional group.
General formula: R-OH (R = alkyl or aryl group)
Nomenclature: Alcohols are named using the suffix "-ol" and the prefix indicating the parent hydrocarbon.
Properties:
- Polarity due to the hydroxyl group
- Can be classified as primary, secondary, or tertiary based on the number of carbon atoms attached to the carbon atom bonded to the hydroxyl group
- Can exhibit hydrogen bonding
Reactions:
- Oxidation reactions (e.g., to form aldehydes or ketones)
- Reduction reactions (e.g., to form alkanes)
- Substitution reactions (e.g., with halogens)
