CLASSIFICATION OF HYDROCARBON
Organic compounds mainly contain hydrocarbon and these hydrocarbon classified into two types i.e.
1-Saturated hydrocarbon (Paraffin)
Name of these type of compound is Alkane. In which (C-C) single bond is present.
2-Unsaturated hydrocarbon (Olefin)
(I) Alkene (C=C) double bond is present.
(II) Alkyne (C=_C) triple bond is present.
ALKANE (C-C)
- General formula is C n H 2n+2
- Alkane = alk + ane
Word root formula (CnH2n+2) Naming
For C 1 - Meth CH 4 Methane
For C 2 - Eth C 2 H6 Ethane
For C 3 - Prop C3 H8 Propane
For C4 - But C4 H10 Butane
For C5 - Pent C5 H12 Pentane
For C6 - Hex C6 H14 Hexane
For C7 - Hept C7 H16 Heptane
For C8 - Oct C8 H18 Octane
For C9 - Non C9 H20 Nonane
For C 10 - Dec C10 H22 Decane
ALKENE (C=C)
- General formula is C n H 2n
- Alkene = alk + ene
Word root Formula (CnH2n) Naming
For C2 - Eth C2 H4 Ethene
For C3 - Prop C3 H6 Propene
For C4 - But C4 H8 Butene
For C5 - Pent C5 H10 Pentene
For C6 - Hex C6 H12 Hexene
For C7 - Hept C7 H14 Heptene
For C8 - Oct C8 H16 Octene
For C9 - Non C9 H18 Nonene
For C10 - Dec C10H20 Decene
ALKYNE (C=_C)
- General formula is C n H 2n-2
- Alkyne = alk + yne
Word root Formula (CnH2n-2) Naming
For C2 - Eth C2 H2 Ethyne
For C3 - Prop C3 H4 Propyne
For C4 - But C4 H6 Butyne
For C5 - Pent C5 H8 Pentyne
For C6 - Hex C6 H10 Hexyne
For C7 - Hept C7 H12 Heptyne
