NEET Chemistry Alkenes MCQ Question
An orbital diagram of ethene shows the overlapping of two sp² hybrid orbitals from each carbon atom to form a σ bond. Which of the following correctly describes the nature of the π bond in ethene?
The π bond is formed by the sideways overlap of two unhybridized p orbitals.
The π bond is formed by the head-on overlap of two sp² orbitals.
The π bond is formed by the overlap of an sp³ orbital with a p orbital.
The π bond is formed by the overlapping of sigma bonds from each carbon.
Correct Answer
Detailed Explanation
The π bond in ethene is formed by the sideways overlap of two unhybridized p orbitals, as shown in the orbital diagrams of ethene. This overlap occurs above and below the plane of the σ bond.
