Double bond consists of:
Correct answer: B. One sigma and one pi bond
- A. Two sigma bonds
- B. One sigma and one pi bond
- C. One sigma and two pi bonds
- D. Two pi bonds
Explanation
A double bond consists of one sigma bond and one pi bond. The sigma bond is formed by the overlap of hybridized orbitals (e.g., sp² hybrid orbitals in ethene) between the carbon atoms, while the pi bond is formed by the overlap of unhybridized p orbitals above and below the plane of the molecule.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
