FINAL - SECTION 6 Flashcards
How many bonds does a neutral carbon form
4
Organic chemistry basic structure
- Each bend or intersection = carbon atom
- Hydrogen is not drawn if bonded to C, but if it is not bonded to C then draw
- Every non-C atom drawn
- Octet + duet rule
- Draw separate bond from molecules (eg. OH, NH2)
Alkanes
Contain only carbon and hydrogen and no double/triple bond
Base names alkanes
- Methane 1C
- Ethane 2C
- Propane 3C
- Butane 4C
- Pentane 5C
- Hexane 6C
- Heptane 7C
- Octane 8C
- Nonane 9C
- Decane 10C
Primary carbon
Bonded to one other carbon
Secondary carbon
Bonded to two other carbon
Tertiary carbon
Bonded to three other carbon
Quaternary carbon
Bonded to four other carbon
Basic rules for naming
- Lowest substituent
- When 2+ same substituents, use prefix di tri tetra, etc
- Substituent alphabetical order
Alkane naming format
Substituent number - substituent name - base name
Number prefix
- Mono 1
- Di 2
- Tri 3
- Tetra 4
- Penta 5
- Hexa 6
- Hepta 7
- Octa 8
- Nona 9
- Deca 10
Iso prefix
When there is a methyl group located on the second carbon of carbon chain
Alkynes
Hydrocarbons with TRIPLE BOND (-yne). Give the first carbon of triple bond the lowest number
If there is more than 1 triple or double bond, what do you do with the number
Write it in the middle, not the front (eg. hex-2-yne)
Alkenes
Hydrocarbons with one or more DOUBLE BOND (-ene)
Which one (alkynes or alkenes) get priority
Whichever gets the lowest number, but if it is a tie then alkene gets priority
Unsaturated hydrocarbon
Refers to alkynes and alkenes cause fewer H
Saturated hydrocarbons
Refers to alkanes cause more H
Diene/triene
Alkenes with 2/3 double bonds
Cis isomer
If 2 substituents on same side of double bond
Trans isomer
If 2 substituents on opposite side of double bond
Aromatic hydrocarbon
Rings with C-C double bond (benzene)
- Phenyl
When benzene is attached to 7+ carbons
Alcohols
Contain a hydroxyl group (-nol)
Alkali hallides
Halogen binder to carbon (ane). Name from the carbon closest to halogen
