Question

The statement that is NOT correct is (A) Carbohydrates are optically active. (B) Lactose has glycosidic linkage between C4 of glucose and C1 of galactose unit. (C) Aldose or ketose sugars in alkaline medium do not isomerise (D) Penta acetate of glucose does not react with hydroxylamine

Tardigrade Admin · Accepted Answer

Aldose and ketose sugars in alkaline medium may be isomerises. Aldose and ketose sugar undergo isomerisation in the presence of alkaline solution of alkaline earth aluminate catalyst.

Q. The statement that is NOT correct is

Carbohydrates are optically active.

Lactose has glycosidic linkage between $C_{4}$ of glucose and $C_{1}$ of galactose unit.

Aldose or ketose sugars in alkaline medium do not isomerise

Penta acetate of glucose does not react with hydroxylamine

Aldose and ketose sugars in alkaline medium may be isomerises. Aldose and ketose sugar undergo isomerisation in the presence of alkaline solution of alkaline earth aluminate catalyst.
