Inversion of cane sugar is a:

Updated On: Mar 27, 2026
  • Zero order reaction
  • Pseudo first order reaction
  • Second order reaction
  • Third order reaction
Show Solution

The Correct Option is B

Solution and Explanation

The acid-catalyzed hydrolysis of sucrose, also known as inversion of cane sugar, yields glucose and fructose. The chemical equation for this process is:

C₁₂H₂₂O₁₁ + H₂O → C₆H₁₂O₆ + C₆H₁₂O₆

Due to water's presence in excess, its concentration remains effectively constant, simplifying the reaction kinetics. This change in kinetic order, from what would theoretically be second-order to effectively first-order with respect to sucrose concentration, classifies the reaction as pseudo-first-order.

The correct classification is: Pseudo first order reaction
