(NR) ALKENES & ALKYNES (double&triple bonds)

- Carbon can form double and triple bonds with Carbon atoms.
- When multiple bonds form fewer hydrogens are attached to the Carbon atom
- Naming rules are almost the same as with Alkanes.
     > The position of the double/ triple bonds ALWAYS has the lowest number and is put in front of the
        parent chain.
- double bonds (ALKENES) end in -ene
- triple bonds (ALKYNES) end in -yne
