Question

One of the following contains a double bond as well as single bonds. This is:

Options

• CO₂

• O₂

• C₂H₄

• C₂H₂

Answer 1

C₂H₄

Explanation:

Ethene (C₂H₄) consists of two carbon atoms connected to each other by a covalent double bond (C = C). Additionally, each carbon atom is bonded to two hydrogen atoms via two single covalent bonds (C-H). Therefore, the entire molecule simultaneously contains one double bond and four single bonds, thereby achieving full structural stability.
