Why does c6h12o6 dissolve in water

Glucose is small 6 carbons and dissolves easily in water because it has a number of polar OH groups attached to its carbons. Glucose sugar readily dissolves in water, but because it does not dissociate into ions in solution, it is considered a nonelectrolyte; solutions containing glucose do not, therefore, conduct electricity. Dissolved sugar molecules are also hydrated, but without as distinct an orientation to the water molecules as in the case of the ions. The sugar molecule contains many -OH groups that can form hydrogen bonds with the water molecules, helping form the sucrose solution.

Sugar dissolves faster in hot waterthan it does in cold water because hotwater has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster.

As they move faster, they come into contact with the sugar more often, causing it to dissolve faster. Solid sugar consists of individual sugar molecules held together by intermolecular attractive forces.

It depends in your definition For non-scientific use, the term 'sugar' refers to the molecule sucrose also called "table sugar" , and these are the white crystals we add to tea and coffee to make it sweeter.

However, to a scientist, the term 'sugar' refers to any monosaccharide or disaccharide. Monosaccharides also called "simple sugars" , such as glucose, contain only one sugar unit per molecule, while di saccharides have 2 sugar units and poly saccarides have many sugars units per molecule see below.

In a list of ingredients, any word that ends with "-ose" is likely to denote a sugar. Glucose is a simple carbohydrate, which means it contains carbon, hydrogen and oxygen. Sugars like glucose C 6 H 12 O 6 with six carbon atoms are referred to as hexoses , and it has one sugar unit so it is a monosaccharide.

Its name comes from the Greek glykos , which means 'sweet'. In one of the world's most important chemists, Emil Fischer , discovered the three sugars, glucose, fructose and mannose. By he was the first chemist to synthesize all three of these sugars starting from glycerol.

He was awarded the Nobel prize in Chemistry. Fischer also confirmed the van't Hoff theory , namely the theory of the asymmetric carbon atom. Chiral carbons have four different groups bonded to them. It is quite remarkable that he also correctly predicted the 3D arrangements of glucose with its several chiral carbons. Emil Fischer and Walter Haworth. Our understanding of sugar chemistry increased further when the Nobel Prize in chemistry was awarded to the sugar chemist Walter Haworth of Birmingham University for his important work on carbohydrates.

Howarth et al found that sugars have a ring-like [Howarth formulae] below left , rather than just a straight-line below right , arrangement of their carbon atoms. Both forms shown right can exist in equilibrium. Glucose ring form and straight line form. When glucose forms the ring structure, it can form two isomers. The isomer where the OH group on C1 is below the plane of the ring is known as alpha-glucose, whereas the one with the OH group above the ring is known as beta-glucose.

The above equation is a gross simplification of Glycolysis , a complex metabolic pathway involving oxidation of glucose.

It shows that the food we eat is ultimately broken down and converted to glucose, which then reacts with the oxygen we inhale to release energy to power the cells in our body. The waste products water and carbon dioxide are excreted either by exhaling or urination, or for plants by evaporation from the pores in their leaves.

The reason glucose dissolves readily in water is because it has lots of polar hydroxyl groups which can hydrogen-bond with water molecules. Sodium chloride, NaCl, is a water-soluble salt that dissociates totally in water. Iodine is not very soluble in water, but produces a slightly yellow solution.

No ions are produced when iodine dissolves in any of these solvents. Bromine is readily soluble in water 0. As Ram Kowshik mentioned, due to the relatively larger size of the molecule, water can induce a dipole on Br2.

So bromine can be dissolved in water, but not as much as a normal polar molecule. The reaction of Sulphur dioxide with water leads to the formation of acid called Sulfurous acid.
