Answer 1

The correct answer is Hydrocarbons.

Key Points

Hydrocarbons are the principal constituents of petroleum and natural gas.
They are organic compounds composed entirely of hydrogen and carbon atoms.
Hydrocarbons are categorized into alkanes, alkenes, and alkynes based on the types of bonds between the carbon atoms.
Petroleum is a complex mixture of hydrocarbons and other organic compounds, and it's found in geological formations beneath the Earth's surface.
Natural gas primarily consists of methane (CH4), with smaller amounts of other hydrocarbons such as ethane, propane, and butane.

Additional Information

Allotropes
- Allotropes are different forms of the same element, where the atoms are bonded together in different ways.
- Examples include carbon allotropes like diamond, graphite, and graphene.
Photolysis
- Photolysis is a chemical process by which molecules are broken down into smaller units through the absorption of light energy.
- It plays a significant role in processes like photosynthesis.
Amorphous
- The term amorphous refers to substances that lack a clearly defined crystalline structure.
- Examples include glass and plastics.
