Periodic acid splits glucose and fructose into formaldehyde and formic acid. Ratio of moles of formic acid in glucose and fructose is

A

`1:2`

B

`5:3`

C

`1:1`

D

`2:3`

Text Solution

Verified by Experts

The correct Answer is:
B
`CHO-CHOH - CHOH - underset("Glucose")(CHOH) - CHOH - CH_(2)OH overset(5HIO_(4)) to 5HCOOH + HCHO + 5HIO_(3)`
`CH_(2)OH - overset(O)overset(||)(C)- underset("Fructose")(CHOH)- CHOH - CHOH - CH_(2)OH overset(5HIO_(4))to 3HCOOH + 2HCHO + 5HIO_(3) + CO_(2) + H_(2)O`
`therefore ` molar ratio is 5:3
