What happens when glucose reacts with hi what does it indicate about the structure of glucose?
What does it suggest about the structure of glucose? Since n-hexane has six carbons connected is a straight chain ,therefore , this reaction suggests that glucose also the six carbon atoms connected in a straight chain.
What happens when glucose is treated with hydrogen iodide?
When glucose is heating with hydrogen iodide, it completely reduces to yield n-hexane. Hydrogen iodide is a reducing agent. When glucose is treated with bromine water, it gives gluconic acid as a product.
What do you mean by prolonged heating?
Prolonged heating at high temperature in the presence of moisture causes hydrolysis (increase in free fatty acid content), oxidation, formation of cyclic fatty acids, polymerization etc.
When glucose react with HI and gives heat and n-hexane is forms what is indicate about this reaction?
Option A: n-Hexane: Glucose in the presence of red phosphorus is when heated with HI – hydroiodic acid, it gives n-hexane. This shows that glucose has a straight six-carbon chain.
What happens when glucose is treated with acetic anhydride?
Glucose reacts with acetic anhydride to form glucose pentaacetate.
What happens when glucose is treated with?
Solution 1. (1) When D-glucose is heated with HI for a long time, n-hexane is formed. (2) When D-glucose is treated with Br2 water, D- gluconic acid is produced. (3)On being treated with HNO3, D-glucose get oxidised to give saccharic acid.
What happens when D-glucose is treated with the following reagents write reaction involved I HI II bromine water III HNO3?
i When D-glucose is heated with HI for a long time n-hexane is formed. ii When D-glucose is treated with Br2 water D- gluconic acid is produced. iii On being treated with HNO3 D-glucose get oxidised to give saccharic acid.
Is glucose on heating with hi it forms n hexane?
Option A: n-Hexane: Glucose in the presence of red phosphorus is when heated with HI – hydroiodic acid, it gives n-hexane. This shows that glucose has a straight six-carbon chain. Option C: Hexanoic acid: It is caproic acid.
How does extreme heat happen?
A heatwave occurs when a system of high atmospheric pressure moves into an area and lasts two or more days. In such a high-pressure system, air from upper levels of our atmosphere is pulled toward the ground, where it becomes compressed and increases in temperature.
What happens when glucose reacts with acetic anhydride?
Glucose react with acetic anhydride to form penta-acetate as a molecule of glucose contains five -OH groups.
What happens when D glucose is treated with the following reagents a hi B acetic anhydride?
Solution 1. (1) When D-glucose is heated with HI for a long time, n-hexane is formed. (2) When D-glucose is treated with Br2 water, D- gluconic acid is produced.
What happens when glucose is treated with bromine water?
Glucose on oxidation with bromine water yields gluconic acid.
