Electron dot structure of ethene class 10

Ethene is an unsaturated hydrocarbon belonging to the Alkene series. ethene is the first member of the alkene series. We will learn how to draw the electron dot structure of ethene.

We will discuss the electron dot structure of ethene through the following points

1. Formula of ethene

2. Electronic configuration of carbon

3. Electronic configuration of hydrogen

4. Find the central atom in the compound

5.Draw the structural formula of ethene

6. Electron dot structure of ethene

 

Formula of ethene

`C_2H_4`

Electronic configuration of carbon

`1s^2 2s^2 2p^2`

Carbon has four valence electrons in the outermost shell.

Electronic configuration of hydrogen

`1s^1`

Hydrogen has one valence electron in the outermost shell.

Find the central atom in the compound

There are two carbon atoms and four hydrogen atoms in an ethene molecule. All hydrogen atoms are arranged around the two carbon atoms.

Structural formula of ethene

Carbon atom requires four electrons to complete its octet and each hydrogen atom requires one electron to complete its octet.

 

Each carbon atom shares its  2 valence electrons with other carbon atoms and forms a double bond  and 1-1 valence electron with two hydrogen atoms through a single bond.

So there is one double between both carbon atoms and a single bond between carbon and hydrogen atoms.

Electron dot structure of ethene

It is also called Lewis dot structure of C2H4.
