Question

Glucose on reduction with Na/Hg and water gives?

(A) Sorbitol

(B) Fructose

(C) Saccharic acid

(D) Gluconic acid

Answer 1

When glucose is treated with sodium amalgam (Na/Hg), it acts as a reducing agent, converting the aldehyde group (-CHO) in glucose to a primary alcohol (-CH₂OH), resulting in the formation of sorbitol (a sugar alcohol).

The correct option is A) Sorbitol

Answer 2

The correct option is (A) Sorbitol

Glucose when reacts with Sodium - amalgam (Na-Hg) or Hydrogen (H₂) which acts as reducing agents in the presence of a catalyst on reduction yields Alcohols (Sorbitol).
