The Correct Option is A

Solution and Explanation

To determine which molecule has all atoms coplanar, we need to focus on the concept of hybridization. Molecules with sp² hybridized carbon atoms are typically coplanar, meaning all their atoms lie in the same plane.

Key Points: 

  • In sp² hybridization, carbon atoms form a trigonal planar structure, where all atoms are in the same plane.
  • Examples of sp² hybridized molecules that are coplanar include:
    • Ethene (C₂H₄): The two carbon atoms are sp² hybridized, and the molecule is flat.
    • Benzene (C₆H₆): The six carbon atoms are sp² hybridized, and the molecule is planar.
    • Formaldehyde (CH₂O): The carbon atom is sp² hybridized, and the atoms lie in the same plane.

If a molecule contains sp² hybridized carbon atoms, it will generally have all its atoms in the same plane (coplanar).

Hydrocarbons

Hydrocarbons can be described as organic compounds that consists only hydrogen and carbon atoms. These compounds are of different types and thereby have distinct natures. Hydrocarbons are colorless gases and are known for discharging faint odours. These have been categorized under four major classes named as alkynes, alkanes, alkenes, and aromatic hydrocarbons. 

Types of Hydrocarbons

  1. Saturated hydrocarbons - Saturated hydrocarbons are those compounds where there is a single bond exists between carbon atoms and are saturated with atoms of hydrogen.
  2. Unsaturated hydrocarbons - Hydrocarbons comprises of at least one double or triple bond between carbon atoms are known as unsaturated hydrocarbons.
  3. Aliphatic hydrocarbons - The term denotes the hydrocarbons formed as an outcome of the chemical degradation of fats. Aliphatic hydrocarbons are basically chemical compounds.
  4. Aromatic hydrocarbons - They are distinguished because of the presence of benzene rings in them. They give away distinct types of aroma. These hydrocarbons comprises of only hydrogen and carbon atoms.
