Question

Identify the hydrocarbon from the given electron-dot structure:

Hint:

Alkanes have only single bonds, alkenes contain double bonds, and alkynes contain triple bonds. Ethene (\(C_2H_4\)) is the simplest alkene with a C=C double bond.

Answer 1

Step 1: Understanding the given electron-dot structure
The given structure consists of: - Two carbon (\(\text{C}\)) atoms, each forming a double bond. - Four hydrogen (\(\text{H}\)) atoms surrounding the carbon atoms. - Each carbon shares two electrons with the other carbon, forming a double bond (\(C=C\)).
Step 2: Identifying the hydrocarbon
- Hydrocarbons are compounds made up of carbon and hydrogen atoms. - The presence of a double bond between two carbon atoms indicates it belongs to the alkene family. - The molecular formula of this compound is \(\text{C}_2\text{H}_4\), which corresponds to ethene (ethylene). Thus, the correct answer is Ethene (\(\text{C}_2\text{H}_4\)).
