Organic Nomenclature

The text discusses the nomenclature and classification of hydrocarbons, including their structural components and the rules for naming them. It highlights the importance of identifying the longest carbon chain, referred to as the parent chain, and the various prefixes and suffixes used to denote the number of carbon atoms and the type of bonds present in the molecule.

Cylic Hydrocarbons

Cycloalkenes

Cyclohexene

Cylcloalkanes

Cyclopentane
Root: -cyclo

Aromatic Hydrocarbons

Benzene/Phenyl
Methylbenzene
When carbon chain has more than 6 carbons the benzene is considered a side group and named phenyl group
Suffix: no suffix
Root: -benzene

Naming

4) Suffix

Remove -e and add -ane
Indicates what type of hydrocarbon it is

3) Prefix

4th postion and 2 carbons in a branch
Branches

Number of carbons that aren't connected to the parent chain

Given postions and names of any branches

2) Root

8 carbon atoms
Denotes the number of C atoms in longest parent chain

1) Parent Chain

Longest carbon chain
Is the longest chain of carbons

Basic Alkene/ane/yne

Unsaturated Due to double/triple bond, less H bonds with C atoms

Alkynes
Propyne
Suffix: -yne
Triple bond between carbons
Alkenes
Trans An isomer in which largest groups on C atoms are attached on the opposite sides

Trans-2-butene

Cis An isomer in which largest groups on C atoms are attached on the same side

Cis-2-butene

Propene
Suffix: -ene
Double bond between carbons

Saturated More H bonds with C atoms due to single bond

Alkanes
Propane
Suffix: -ane
Each molecule differes from prevous by adding -CH2- (homologous series)
Single bonds between carbons

Functional Groups

Double Bonded Groups

Carbonyl Group
Ketones

Suffix: -one

Adding -oxy to branches

2-ethoxypropane

Haloalkanes/Alkyl Halides
Named with prefixes: (fluoro-,chloro-,bromo-,iodo-)

Trichloromethane

Hydroxyl Group
Alchohols

Tertiary The carbon with the hydroxyl is bonded to three other carbon

C has no H bonds and 3 R bonds

Secondary The carbon with the hydroxyl is bonded to two other carbon

C has 1 H bond and 2 R bonds

Primary The carbon with the hydroxyl is bonded to one other carbon

C has 2 H bonds and 1 R bond

Multiple -OHs Diol, Triol, Tetra

Ethane-1,1-diol

Suffix: -ol

Ethanol

Organic Nomenclature

Reactions

Two or more products
Hydrolysis

When water splits a bond into two

Condensation

Two organic molecules join to form one organic molecule with water molecule

Elimination

Reverse of addition where an atom is removed to from a double bond

Substitution

When a functional groupe is replaced with another group

One product
Oxidization

When a reactant is oxidized an another is reduced

Reduction

Creates more bonds with H and fewer with O

Addition

When atoms are added to form a double or triple bond
