Periodic acid splits glucose and fructose into formic acid and formaldehyde. Ratio of formic acid and formadehyde from glucose and fructose is:
Options:
Answer:
D
Solution:
Periodic acid (HIO₄) cleaves vicinal diols present in glucose and fructose.
During cleavage, carbon atoms are converted into formic acid (HCOOH) and formaldehyde (HCHO) depending on their position.
Glucose and fructose give different cleavage patterns due to different structures.
The correct ratio of formic acid and formaldehyde formed is (D) 5/1 and 3/2.
