What is the Difference Between Monosubstituted and Disubstituted Alkene?

🆚 Go to Comparative Table 🆚

The main difference between monosubstituted and disubstituted alkenes lies in the number of carbon-based substituents attached to the double-bonded carbon atoms of the alkene. Here are the key differences between the two:

  1. Number of Substituents: A monosubstituted alkene has only one carbon-based substituent attached to the double-bonded carbon atoms, while a disubstituted alkene has two carbon-based substituents attached to the double-bonded carbon atoms.
  2. Stability: Disubstituted alkenes are more stable than monosubstituted alkenes due to the increased number of substituents, which helps to stabilize the molecule.
  3. Hydrogen Atoms: Monosubstituted alkenes have three hydrogen atoms, whereas disubstituted alkenes have two hydrogen atoms.

In summary, monosubstituted alkenes have only one carbon-based substituent attached to the double-bonded carbon atoms, while disubstituted alkenes have two carbon-based substituents. Disubstituted alkenes are more stable than monosubstituted alkenes due to the increased number of substituents, and they have two hydrogen atoms compared to the three hydrogen atoms found in monosubstituted alkenes.

Comparative Table: Monosubstituted vs Disubstituted Alkene

The difference between monosubstituted and disubstituted alkenes lies in the number of carbon atoms bonded to the double-bonded carbon atoms in the alkene. Here is a comparison table highlighting the differences:

Feature Monosubstituted Alkene Disubstituted Alkene
Number of Substituents One carbon atom bonded to one of the double-bonded carbon atoms Two carbon atoms bonded to either the same carbon or two different carbon atoms
Substituent Locations Substituent can be an aliphatic group or an aromatic group, such as methyl, ethyl, or phenyl Substituents can be attached to one or both of the carbons surrounding the double bond
Stability Generally less stable than disubstituted alkenes Generally more stable than monosubstituted alkenes

For example, a monosubstituted alkene may have substituents like a methyl group, ethyl group, or phenyl group, and it contains 3 hydrogen atoms attached to the other positions. In contrast, a disubstituted alkene has two substituents attached to one or both of the carbons surrounding the double bond, making it more stable than a monosubstituted alkene.
