Question

When sucrose is heated with conc. Hno3 in presence of v2o5?

Answer 1

Answer:

A piece of red glass is heated till it glows in dark. ... The oxidation of sucrose with conc. HNO3 in presence of V2O5 leads to the formation of 1,6- hexanedioic acid. —T/F 23. When one mole ...

Answer 2

Solution:

When sucrose is heated with conc.$HNO_3$ in presence of $V_2O_5$ catalyst, then oxidation of sucrose takes place.

Sucrose on oxidation in presence of conc.$HNO_3$  and $V_2O_5$ catalyst gives Oxalic acid.

$C_{12}H_{22}O_{11} + 9O_2 \ \overrightarrow {V_2O_5} \ 6(COOH - COOH) + 5H_2O$

conc.$HNO_3$ is an oxidising agent and provides oxygen to sucrose for oxidation.
