What types of hybridization of carbon are in the compound ethene CH2CH2?
The types of hybridization of carbon in the compound ethene (CH2CH2) is sp2 hybridization.
In ethene, each carbon atom forms a double bond with the other carbon atom, resulting in the formation of a pi bond and a sigma bond. This requires the carbon atoms to have three hybridized orbitals that are arranged in a trigonal planar geometry.
The process of hybridization involves the mixing of one s orbital and two p orbitals, resulting in three sp2 hybrid orbitals. These three sp2 hybrid orbitals are used to form sigma bonds with other atoms or other hybridized orbitals. The remaining p orbital of each carbon atom forms a pi bond by overlapping with each other.
To determine the hybridization state of carbon atoms in ethene (CH2=CH2), we need to analyze the molecular structure.
1. Draw the Lewis structure for ethene:

H H
2. Count the number of sigma bonds and lone pairs around each carbon atom.
- The left carbon atom has only sigma bonds (2 sigma bonds) and 0 lone pairs.
- The right carbon atom also has only sigma bonds (2 sigma bonds) and 0 lone pairs.
3. Determine the hybridization by using the following rules:
- For each sigma bond, one hybrid orbital is needed.
- Each lone pair requires one hybrid orbital.
Based on this, we can conclude that each carbon atom in ethene is sp2 hybridized.
Therefore, the hybridization of carbon in ethene (CH2=CH2) is sp2.
To determine the types of hybridization in a compound, we need to examine the bonding arrangement of its atoms. In the case of ethene (C2H4), we can determine the hybridization of carbon by following these steps:
Step 1: Draw the Lewis structure of the compound.
In ethene, we have two carbon atoms connected by a double bond, and each carbon atom is attached to two hydrogen atoms.

Step 2: Count the number of regions of electron density around each carbon atom.
Each single bond and lone pair count as one region of electron density. In ethene, both carbon atoms have two regions of electron density. One region comes from the double bond with the other carbon atom, and the other region comes from the bond with the hydrogen atom.
Step 3: Determine the hybridization based on the number of regions of electron density.
The following are the common hybridization patterns based on the number of regions of electron density:
- Two regions of electron density: sp hybridization
- Three regions of electron density: sp2 hybridization
- Four regions of electron density: sp3 hybridization
Since each carbon atom in ethene has two regions of electron density, they undergo sp2 hybridization.
Therefore, in the compound ethene (CH2CH2), the carbon atoms are sp2 hybridized.
