Based on Figure 5.2a and the accompanying text, which components are contributed by the two reacting molecules to form a water molecule during a dehydration reaction?

  • A: One provides a hydroxyl group (-OH) and the other provides a hydrogen (-H).
  • B: Both provide a hydroxyl group (-OH).
  • C: One provides a hydrogen (-H) and the other provides an oxygen (-O).
  • D: Both provide a hydrogen (-H) and one provides an oxygen (-O).

Explanation

The text states: 'Each reactant contributes part of the water molecule that is released during the reaction: One provides a hydroxyl group -OH , while the other provides a hydrogen -H Figure 5.2a .' Figure 5.2a visually confirms this.
