Alkanes are saturated aliphatic hydrocarbons, namely open-chain hydrocarbons with carbon and all bonds are single bonds. Alkane compound having the formula:
CnH2n + 2
(JamesE. Brady)
The names of ten alkanes with the number from 1 to 10 carbon atoms contained in Table 5.1. This is the basis of the names of all organic compounds.
Number of Atomic Molecular Formula C Major
1 Methane CH4
2 C2H6 Ethane
3 C3H8 Propane
4 C4H10 Butane
5 C5H12 Pentane
6 C6H14 Hexane
7 C7H16 heptane
8 C8H18 octane
9 C9H20 Nonana
10 C10H22 decane
cluster Alkyl
Alkyl group is an alkane that has lost one atom H. The alkyl group can be written by using the formula:
CnH2n + 1
By replacing one H atom, then his name will also be changed from methane to methyl. Here are some commonly used alkyl group.
Formula Name Alkyl
CH3 - Methyl
C2H5 - Ethyl
C3H7 - propyl
C4H9 - Butyl
Methyl and ethyl groups of each kind only, namely:
Propyl cluster there are two types, namely:
Meanwhile, a butyl group, there are four types, namely:
