Multiple Choice

Which of the following is the best description of a coupled reaction in organic chemistry?

A reaction where a catalyst is used to increase the rate of reaction without being consumed.

A reaction where two reactants form a single product without any energy exchange.

A reaction where two reactions occur simultaneously, with one providing energy for the other.

A reaction that involves the transfer of electrons between two species.

Verified step by step guidance

Understand the concept of a coupled reaction: In organic chemistry, a coupled reaction involves two reactions that occur simultaneously, where the energy released by one reaction is used to drive the other reaction.

Identify the key components of a coupled reaction: One reaction is exergonic (releases energy) and the other is endergonic (requires energy). The energy from the exergonic reaction is used to power the endergonic reaction.

Analyze the given options: Compare each option to the definition of a coupled reaction. Look for the option that describes two reactions occurring together with energy transfer between them.

Eliminate incorrect options: Remove options that do not involve simultaneous reactions or energy transfer. For example, a catalyst increasing reaction rate without being consumed does not describe a coupled reaction.

Select the correct description: Choose the option that best matches the definition of a coupled reaction, which is 'A reaction where two reactions occur simultaneously, with one providing energy for the other.'
