Inversion of cane-sugar :
The hydrolysis of sucrose through boiling along with a mineral acid or through enzyme invertase, generates a mixture of equal molecules of D-glucose and D-fructose.
Sucrose solution is dextrorotatory. Its particular rotation is +66.5°C although on hydrolysis, it transforms into laevorotatory. The specified rotation of D-glucose is +52°C and of D-fructose is -92°C. henece, the net partcular rotation of an equimolar mixture of D-glucose and D-fructose is.
So, in the procudure of hydrolysis of sucrose, the particular rotation changes from +66.5°C to -20°C, that is from dextro it becomes laevo and it is said that inversion has occur. The process of hydrolysis of sucrose is thus termed as inversion of sugar and the hydrolysed mixture comprising equal molar quantities of D-glucose and D-fructose is known as invert sugar. The enzyme that provides the inversion is termed as invertase.

explanation
The intramolecular product tetrahydrofuran results from an internal nucleophilic substitution reaction of the alkoxide on the alkyl halide. The intermolecular product 1,4-butanedio

Physical properties of monohydric alcohols (a) Character - Monohydric Alcohols are neutral component. These comprise no effect on litmus paper. This is analytical investigation
when a 0.800g sample of cacl2 is dissolved in 9.85g of water in a microscale calorimeter, the temperature of the solution rose from 23.4 to 35.8
A solvated electron is a free electron in (solvated in) a solution, and is the least possible anion. Solvated electrons happen widely although they are often not practical directly
reasons of failure
