holtadit:
given somethin like:

CH3–C=CH2
       l
     CH3

How would you draw the displayed structural formula or line bond formula ?

In short i want to know how to take a condensed structural formula and turn it into a displayed structural formula and then be able to name the organic compound.

DONOT give me links to websites; please try and explain this to me instead (i have researched this extensively)

holychalice:
do u mean like this :
C4H8 - nw as there is 1 double bond ... so its an alkene - 4 carbon atoms- butene
nd wen u turn into structural -
   H     H
    l      l
H-C-C=C-H                   Cuz d point is every C atom should be bonded with 4 other atoms ..... nd since u hav this u can make isomers
    l   l                          And in naming this ... ders a CH3 which is mthyl .... nd d upper chain which is d longest ...
   H   l                         dat contains 3 carbon atoms nd a duble bond so propene .... so 2-methyl-propene (diagram may help)
    H-C-H
        l
       H

--- End quote ---

it shud be 2-methyl propene

2 becoz the methyl group is hanging from the 2nd carbon

methyl because its a methyl group attached

butene because there is a double bond and its 3carbon excluding the methly

holtadit:
You must be wrong because the 2003 june paper IGCSE chem. says that it is bu-2-ene.

How is this possible ?? Even i thought it was 2-methylpropene

nid404:
yes it is indeed 2methyl propene
