What is the Electron dot structure of hydrocarbons?
Electron dot structure is a representation of the valence electrons of an atom where the dots are used to represent the valence electrons.
How to Create the electron dot structure of hydrocarbons?
Let us understand the steps to create the electron dot structure of hydrocarbons using the following examples:
(i) Electron dot structure of methane
Step 1: Draw carbon atoms with valence electrons using cross-mark (x).
Methane has one carbon atom and its valency is four. It will be represented as shown below:
