Question

Draw the structure(s) of all of the alkene isomers, C₆H₁₂ , that contain a methylene group. Consider E/Z stereochemistry of alkenes.

Answer 1

There are two alkene isomers of C6H12 that contain a methylene group: 2-methylpentene and 3-methylpentene.

Step-by-step explanation:

When drawing the structures of alkene isomers containing a methylene group, we can start with the general formula C6H12.

One isomer that contains a methylene group is 2-methylpentene. The structure can be drawn as:

H H H
| | |
C C = C
| | |
H H H
Methyl

Another isomer is 3-methylpentene, which can be drawn as:

H H H
| | |
C C C
| | |
H H H
Methyl

These are the two alkene isomers of C6H12 with a methylene group.
