Question

Which of the following forms of energy is not one of those to have been involved in the production of large organic molecules in the primitive reducing atmosphere?

Options

• Radioactivity

• Electrical energy

• Radiation from the Sun

• Sound

Answer 1

Sound

Explanation:

The main forms of energy contributing to the abiotic synthesis of organic molecules in the early Earth’s reducing atmosphere included radioactivity, electrical energy (from lightning), and radiation from the Sun. Sound energy does not play a role in these chemical processes leading to the formation of organic compounds.
