Question

HOCH 2 ⋅ CH 2 OH on heating with periodic acid gives (A) HCOOH (B)  (C)  (D) CO 2

When 1,2 -diol like ethylene glycol is treated with HIO 4, each alcoholic group is oxidised to a carbonyl group by HIO 4 Since in glycol, both the -OH groups are terminal, so oxidation would yield two formaldehyde molecules. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/31dd482854922b1241980feb453a04b8-.png" />

Q. $H OC H_{2} \cdot C H_{2} O H$ on heating with periodic acid gives

$H COO H$

$C O_{2}$

When $1, 2$ -diol like ethylene glycol is treated with $H I O_{4},$ each alcoholic group is oxidised to a carbonyl group by $H I O_{4}$

Since in glycol, both the - $O H$ groups are terminal, so oxidation would yield two formaldehyde molecules.
