Ochem Flashcards
Naming steps
- Find longest carbon chain 2. The highest priority functional group will provide the suffix 3. The carbon numbered 1 will be the one closest to the highest priority functional group 4. A substitutents name will be placed at the beginning as a prefix, followed by the name of the longest chain.
Priority in functional groups
The more oxidized a carbon is, the higher priority it has in the molecule. Oxidation state increases with more bonds to atoms other than carbon and hydrogen However Double bond > triple bond
t-butyl
isopropyl
isobutyl
Pic
sec-butyl
Pic
Hydrocarbons
Compounds that contain only carbon and hydrogen atoms
Alkanes
Have the formula CnH(2n+2) Methane (one carbon) Ethane (2 carbons) Propane (3 carbons) Butane (4 carbons) Pentane Hexane Heptane Octane Nonane
Alcohols
The hydroxyl group (OH) > double bond + triple bond Will be given a lower number If the alcohol is not the highest priority functional group, then it is named as a substituent (hydroxy-)
Ethanol
Pic
Ethyl alcohol
Pic
Isopropyl alcohol
Pic
Diols
Alcohols with two hydroxyl groups. Indicated with suffix -diol
Geminal diols
Diols with hydroxyl groups on the same carbon. AKA hydrates. They spontaneously dehydrate to produce carbonyl compounds
Vicinal diols
Diols with hydroxyl groups on adjacent carbons
