Alkanes, Alkenes, Alkynes & Halides, Nitro, Alcohol, Ketones, Aldehydes--By Nemo Jin

Alkane
--all carbon atoms bonded by single bond
--general form "CaH2a"
--alkyl groups: alkane lost one hydrogen



Alkene & Alkyne
--"ene" double bonded carbon atoms
--"yne" triple bonded carbon atoms
--same naming rules, give double/triple bond the lowest number
--larger groups are diagonal: trans
--larger groups are at either bottom or top: cis

Ex.
















 Ex.

















Functional Groups
--most reactive part of the molecule
--insoluble in water
--F is less reactive; Cl, Br are the most reactive ones
--NO2: tend to be explosive

           F = fluoro
            I = iodo
          Cl = chloro
          Br = bromo
      NO2 = nitro


Ex.





Alcohol
--using the largest chain containing the OH group
--replacing the "e" ending in parent hydrocarbon chain with "ol"
--give OH the lowest number

general form:


Ketone &Aldehyde
--Aldehyde:
   -double bonded oxygen at the end of main chain
   -change the ending to "al"
--Ketone:
   -double bonded oxygen that's not on either end
   -change the ending to "one"
