Why is d glucose dextrorotatory but d fructose is levorotatory?

I think you mean D-fructose is leavorotatory. D is a convention that compares a steroisomer to glyceraldehyde and does not define the right/left roatoion of plane polarised light.

Dextrose chemical formula?
The chemical formula of Dextrose is C6H12O6. Dextrose is the name sometimes given to dextrorotatory glucose, which is in turn shortened 'D-glucose'.
What happen when d-glucose reacts with bromine in water?
Bromine Water disappear thus forming Gluconic Acid
What is the chemical compound C7O6H14?
/\/\/
How the d-block group number relte to the number of outer s and d electrons?
The d-block elements have two electrons in their outermost s sublevels. The group 3 elements have one d electron in their outermost d sublevel, the group 4 elements have two d electrons, adding one additional d electron with each subsequent group until group 12 in which the elements have ten d electrons.
What is vitamin D used for?
The vitamin D has a role in Cancer recovery and prevention
What happens during the inversion of sucrose?
Invert Sugar is a mixture of equal parts of Glucose (Dextrose) & Fructose resulting from the hydrolysis of Sugar (Sucrose). It is found naturally in friuts & honey and produced artficially for use in the food industry.
Which sugar is called invert sugar?
when sucrose is hydrolysed it turns into glucose and fructose. fructose is laevo rotatory whereas glucose is dextrorotatory sucrose is also dextrorotatory but amout of laevo rotation of fructose is able to overcome the dextro rotation of glucose. hence the product is laevo rotatory an d reactant dextrorotatory hence sucrose is an invert sugar.
How do you distinguish glucose and fructose?
Glucose is an aldose whereas fructose in a ketose. There is a simple qualitative test for distinguishing between D-Glucose and D-Fructose.
What are two monosaccharides that will make the disaccharide sucrose?
Fructose and glucose are found in sucrose.
Chemical composition of sucrose?
a molecule of fructose and a molecule of glucose
Dextrose chemical formula?
The chemical formula of Dextrose is C6H12O6. Dextrose is the name sometimes given to dextrorotatory glucose, which is in turn shortened 'D-glucose'.
How does the Fischer projection of D-fructose differ from D-glucose?
D-glucose is an aldehyde with the carbonyl group on carbon 1; D-fructose is a ketone with the carbonyl group on carbon 2
Examples of monosaccharide carbohydrates?
Glucose.
Is sucrose a substance or a mixture?
sucrose is a unique chemical compound containing a glucose and fructose unit (both of which exhibit chirality) connected by an alpha/beta linkage. in nature all sugar units are comprised of dextrorotary molecules. As far as synthetic manufacture is concerned there are 4 potential anaolgues of sucrose consisting of :d-d glucose/fructose, L-D glucose/fructose, D-L glucose/fructose, and L-L glucose/fructose
Why osazone obtained from D-glucose and D-fructose have the same melting points?
glucose and fructose form same osazone crystals because carbon no 1 to carbon no 6 are identical both in glucose and in fructose
What are three things in monosaccharide?
glucose, fructose. and galactose! :D
What ketohexose and aldohexose are present in melezitose?
β-D-fructose and α-D-glucose
