25

Prefixes for carbon atoms

  • Compounds with single bonds are alkanes: -ane

  • Compounds with double bonds are alkenes: -ene

  • Compounds with triple bonds are alkynes: -yne

media

26

Therefore a hydrocarbon with 2 carbons is:

  • Alkane: ETHANE

  • Alkene: ETHENE

  • Alkyne: ETHYNE

Question image

What is the name of this compound?

1

octane

2

octene

3

octyne

31

In nomenclature of unsaturated hydrocarbons (alkenes and alkynes) you must consider the position of bonds

  • The main chain will be the one with double or triple bonds, highest number of carbon atoms and more branches.

  • The numbering must start from the end closest to the double/triple bond.

32

Start numbering from the end nearer the double bond

  • The locator for the bond is the lowest number.

  • Alkenes or alkynes with two or three carbons do not need numbers.

  • The name of this alkene is 2-heptene or hept-2-ene.

33

The name of this alkyne is ...

  • 3-nonyne or non-3-yne.
