C2H4 polarity

Ethylene (C2H4) is an organic compound that consists of hydrogen and carbon. It has a colorless flammable gas with a musky and sweet odor.

C2H4 has two Ch and four H molecules. When ethylene is oxidized, it produces ethylene oxide, but ethylene is hydrolyzed, it produces ethylene glycol.

Ethelene has a hormone that is mostly known for plant growth and development.

Is C2H4 Polar Or Nonpolar

Ethylene structure
Ethylene (C2H4)

Explanation 1: 

The ethylene (C2H4) is a nonpolar molecule due to the nonpolar covalent C-H bond’s special appearance. In C2H4, there are excessive nonpolar covalent C-H bonds. The hydrogen atoms are arranged in a symmetrical shape, which is surrounding two carbon.

Explanation 2:

The ethylene (C2H4) is a nonpolar molecule because the molecule shape is like two symmetrical triangles. In C2H4, C and H’s electronegativity is different, The C-H bonds are polar, and the C-C bond is nonpolar. Also, the charge distribution is even since the molecule becomes symmetrical, resulting in a nonpolar molecule.

Explanation 3:

The ethylene (C2H4) is a nonpolar molecule because the electronegativity of both atoms is very similar. The electronegativity of hydrogen is 2.2, and the electronegativity of carbon is 2.55. The hydrogen carbon bonds are nonpolar, which resulting in a polar molecule.

Explanation 4:

The ethylene (C2H4) is a nonpolar molecule because of its geometrical shape. Also, the dipole moment of C2H4 is zero, resulting in a nonpolar molecule.

With that, it’s also essential to know about the I2SF3 and BF3 polarity.


C2H4 is nonpolar because of its shape and mostly the same electronegativity.

C2H4 Molecular Geometry

The molecular geometry of C2H4 is a trigonal planar with respect to carbon left and right. Many people are confused that C2H4 is tetrahedral, but it’s not tetrahedral C2H4 has a trigonal planar shape.

The molecular shape is expected to be a flat triangle around each carbon atom.


Simple is that the C2H4 molecular geometry is trigonal planar.

C2H4 Lewis Structure

Dot Diagram of C2H4

In the Lewis structure of C2H2, the use of a double bond is necessary.

To draw the C2H4 Lewis structure, follow the below instructions.

  • First of all, find out the total number of valence electrons in the C2H4 using the periodic table.
  • The carbon is in group four but sometimes written 14, so it has four valence electrons. The hydrogen is in group 1 and has one valence electron. 
  • Once you know that carbon electron valency multiplies it with 2, which becomes 4(2)= 8, now do the same process with hydrogen 1(4)=4. Add hydrogen + carbon valence electrons to find the total valence electrons. 4+8= 12.
  • We have a total of 12 valence electrons, spread them around.
  • Put the hydrogen on the outside of carbon is given in the above figure. 
  • Put the two electrons between each bond to make a chemical bond. 
  • Take the two valence electrons in the center to make a double bond.
  • Make sure the hydrogen has two valence electrons so their octet will be full.

Try to draw the Lewis structure of C2H4 itself without watching the video. Once you draw it so, compare it with the video and see if you have made any mistakes correct them.

Hybridization Of Ethene (C2H4)

The C2H4 has 2 CH and 4 H molecules, and the carbon atom contains 6 electrons. A hydrogen atom has 1 electron.

The hybridization of C2H4 is sp2, between two carbon atoms sigma and pi bond formed.


The ethene molecule has sp2 hybridization.

Bond Angle Of Ethene (C2H4)

In ethene (C2H4) each bond angle of H-C-H is 116.6° and each H-C-C bond angle is 121.7°.

There is no free rotation in carbon-carbon double, and all six atoms of the ethene lie in the same plane.


The bond angle of C2H4 is 120°.

Is C2H4 Ionic Or Covalent

The C2H4 have double covalent bond because the structure of C2H4 consists of the double covalent bond between the two carbon atoms. Do you want to find a bond by trick? Here is how to find a bond that is ionic or covalent.


Simple is that C2H4 have double covalent bond.

Is C2H4 A Lewis Acid Or Base

C2H4 is a base, not Lewis acid. If someone asks you which one of the following is not a Lewis acid? what will be your answer? Don’t read the below answer.

  • C2H4
  • BF3
  • FeCl3
  • SiF4


C2H4 is not a Lewis acid because the molecules in BF3 and FeCl3 in the central atom have an incomplete octet. The SiF4 in the central atom, and according to Lewis’s concept, these three are Lewis acid.


Simple is that C2H4 is a base, not Lewis acid.

Properties Of Ethene (C2H4)

  • The molar mass of the C2H4 is 28.054 g·mol−1.
  • Its acidity is 44.
  • It is slightly soluble in water.
