$B$ and $E$

Vedclass · Answer

(B) Glucose contains an aldehyde group $(-CHO)$,but it exists primarily in a cyclic hemiacetal form in equilibrium with a small amount of the open-chain form.Due to this cyclic structure and the low concentration of the free aldehyde group,glucose does not undergo certain reactions typical of aldehydes.Specifically,glucose does not give Schiff's test $(B)$ and it does not form the hydrogen sulphite addition product with sodium bisulphite ($NaHSO_3$,$E$).Therefore,the correct reagents are $B$ and $E$.

List-$I$	List-$II$
$A$. $\alpha$-Glucose and $\alpha$-Galactose	$I$. Functional isomers
$B$. $\alpha$-Glucose and $\beta$-Glucose	$II$. Homologous
$C$. $\alpha$-Glucose and $\alpha$-Fructose	$III$. Anomers
$D$. $\alpha$-Glucose and $\alpha$-Ribose	$IV$. Epimers

The reagents with which glucose does not react to give the corresponding tests/products are
$A$. Tollen's reagent
$B$. Schiff's reagent
$C$. $HCN$
$D$. $NH_2OH$
$E$. $NaHSO_3$
