🇬🇧🇬🇧
Organic Chemistry
Compounds that contain carbon atoms in living things.
Exceptions
CO3 - CO2 - C ( Oxides, carbides, carbonates).
Types of organic chemistry
Hydrocarbons, Other organic compounds
Isomers
Compounds with the same molecular formula but with a different structure
X
A
Hydrocarbons
Organic with C and H only
Examples of hydrocarbons
Alkane, Alkene, Alkyne, Cycloalkanes, Aromatics
Hydrocarbons are classified into
Saturated and Unsaturated Hydrocarbons
Saturated Hydrocarbons
Contain only single bonds. As: Alkanes and Cycloalkanes.
Unsaturated Hydrocabons
Contain at least one double or triple bond only. As: Alkene, Alkyne, Aromatics.
Bond of alkanes
Alkanes form only single bonds
Perfix
-ane
Molecular formula example
N=4 C4H2(4)+2=C4H10
Classification of Alkanes
Since alkanes have single bonds; it is saturated.
Bonds of Cycloalkanes
Cycloalkanes have only single bonds. However, it is arranged as a cycle( cyclic).
CnH2n
General Molecular formula of Cycloalkanes
Prefix
Cyclo Prefix ane
:.....
It starts from 3 C (3rd carbon)
Classification of Cycloalkanes
Since cycloalkanes have single bonds only; it is saturated.
Bond of alkenes
At least one Double bond
Example of using the prefix
Butene Exception: Methene cant be considered an alkene.
:...
Starts from 2 C (2nd carbon)
Classification of Alkenes
Since alkenes use double bonds only; it is unsaturated
Bond of alkynes
At least one Triple bond
Example of using the prefix
Butyne Exceptions: Methyne cant be considered as an alkyne.
Molecular formula example
N=4 C4H2(4)-2=C4H6
:.....
Starts from C2 (2nd carbon)
Classification of Alkynes
Since alkynes use triple bonds; it is unsaturated
Structural formula
Hexagon with a ring
Prefix
Benzene
Other organic compounds
C, H + a non metal
Examples of other organic compounds
Alcohols, Ethers, Amines
Functional group of alcohols is
OH group( hydroxyl group)
Molecular formula example
N=4 C4H2(4)+2 OH=C4H10OH
Butanol
Prefix example
OH
It takes the least possible number
Prefix
Branch+ prefix + ether
Molecular formula example
N=4 C4H2(4)+2 O= C4H10O
Functional group of Amines
N group (nitrogen)
Prefix
Branch+ prefix +amine
.....
Starts from 4 C (4th carbon)
Example of using the prefix
Dimethylethylamine
