Question

When methyl d glucopyranoside is oxidised with periodic acid?

Answer 1

When methyl D-Glucopyranoside is oxidized with periodic acid, two moles of the oxidizing agent are consumed per mole of the sugar. Periodic acid cleaves vicinal diols to form carbonyl compounds

Answer 2

Explanation:

The periodic acid cleaves the carbon-carbon bond containing hydroxyl groups.It oxidizes methyl d-glucopyranoside into formic acid and formaldehyde.

$C_6H_{12}O_6+5HIO_4\rightarrow 5HCOOH+HCHO$

According to recation, methyl d-glucopyranoside that is glucose consumes five moles of periodic acid to form a formic acid and formaldehyde .
