The reaction between ethane and chlorine in sunlight is a Free radical substitution. Here's a step-by-step breakdown of the mechanism:

1. Initiation: The reaction starts with the homolytic fission of a chlorine molecule to form two chlorine radicals. This is caused by the absorption of ultraviolet light. The bond breaks evenly and each chlorine atom keeps one of the shared pair of electrons.

2. Propagation: In the first propagation step, a chlorine radical collides with an ethane molecule. It pulls off one of the hydrogen atoms to create hydrochloric acid, leaving behind an ethyl radical. In the second propagation step, the ethyl radical reacts with a chlorine molecule to form chloroethane and another chlorine radical.

3. Termination: The reaction can be terminated if two radicals collide to form a molecule. For example, two chlorine radicals could combine to form a chlorine molecule, or a chlorine radical and an ethyl radical could combine to form chloroethane.

So, the correct answer is A. Free radical substitution.
