Functional Groups

-Functional Groups-

Functional Groups: Specific group of atoms whihch exists in a molecule and gives a specific properties to a molecule.

Ex: They can lead the molecule into many different other form such as acid, base or both


-Here is some example of Functional Group-

A.) Alcohols
-Alcohol contains OH in the compound (Organic Compound ofcourse~)

-For example: CH3-OH, CH3-CH2-OH

-Alcohol is soluable in water and non-polar hydrocarbon chain tends to make alcohols insoluable in water

-All alcohols are poisonous (So don't drink alcohol too much~You will die!)


B.) Aldehyde
-Aldehyde has C=O group at the end of the hydrocarbon chain

-Aldehyde can simply look like this: -CHO


C.) Ketones
-Ketone is organic compound that have C=O group similar to Aldehyde but not at the end of the Hydrocarbon Chain


D.) Ethers
-Ether is compound in which an oxygen joins two hydrocarbon groups

-Fact: Ehers can be act as anaesthetic purposes

Ex of Ethers: CH3CH2-O-CH2CH3


E.) Amines
-Amine is an organic compound containing an NH2 group

-Amine is basic and reacts with acid

-It has fishy-like odour (Which means it smells horrible)


F.) Amide
-Amide is an organic compound containing a CONH2 Group


G.) Carboxylic Acid
-Carboxylic Acid has COOH group.

-Also refered to as Organic Acids


H.) Esters (Hm? Don't we have name Ester in school or something?)
-Ester is compound that has COO group which joins two hydrocarbon chains
