Chapter 7: Problem 43

This section contains multiple choice questions. Each question has 4 choices (a), (b), (c) and (d), out of which ONLY ONE is correct. The products of oxidation of glucose by bromine water and conc.HNO, are respectively (a) gluconic acid and glucaric acid (b) oxalic acid and saccharic acid (c) glucaric acid and gluconic acid (d) saccharic acid and oxalic acid

Short Answer

Expert verified
Answer: Gluconic acid and saccharic acid.

Step by step solution

01

Oxidation of glucose by bromine water

Bromine water acts as a mild oxidizing agent. When glucose is exposed to bromine water, the aldehyde group is selectively oxidized, forming gluconic acid as the product.
02

Oxidation of glucose by concentrated HNO₃

Concentrated nitric acid (HNO₃) is a strong oxidizing agent. When glucose undergoes oxidation by HNO₃, both the aldehyde group and primary alcohol group get oxidized, forming saccharic acid as the product.
03

Identify the correct option

Now that we know the products of both reactions, we can identify the correct option. From our analysis, oxidation of glucose by bromine water results in gluconic acid, and oxidation of glucose by concentrated HNO₃ results in saccharic acid. So, the correct answer is option (a).
