Organic chemistry Flashcards
Organic Compounds
Contain CARBON bonded to HYDROGEN
- over 90% of all compounds
EX: carbohydrates, plastics, synthetic fibres, lipids, petroleum, dyes
Properties of Organics Compounds
- covalent bonding
- low mp and bp
- variable states of matter (at room temp)
- most: insoluble in polar solvents
- non-conductors in solution form
- react with oxygen to produce CO2, H2O, energy
- may have isomers
Inorganic Compounds
Do not contain Carbon bonded to Hydrogen
- less than 10%
EX: water, salt, polyatomic compounds, cyanides, carbonates
Properties of Inorganic Compounds
- ionic bonding
- high mp and bp
- solid form (at room temp)
- soluble in polar solvents
- conductors in solution form
- do not react wth O2
- no isomers
Carbon
Foundation for life:
- bonding capacity of 4 (4 valence electrons) = 4 covalent bonds
- forms bonds with itself and other atoms
- atoms join together to form chains and rings
- variety of bonds (single, double, triple)
Hydrocarbons
Organic compounds composed of carbon and hydrogen
- backbone of all organic compounds
- nonpolar, insoluble in water
- Aliphatic and Aromatic
Aliphatic
Chains and rings
- alkanes
- alkenes
- alkynes
Aromatic
Based on benzene
C6H6
Saturated
Containing only single bonds
Unsaturated
Containing a double/triple bond
Alkane
C(n)H(2n+2)
Naming: suffix “ane”
- saturated

Alkene
C(n)H(2n)
Naming: suffix “ene”
- unsaturated
