Synthetic detergents are cleansing agents which have all the properties of soaps but which actually do not contain any soap.What is the solution to above problem ? How can we save our environment.

Synthetic detergents are cleansing agents which have all the properties of soaps but which actually do not contain any soap. What is the main problem in using detergents?

If water contains dissolved calcium hydrogen carbonate, out of soaps and synthetic detergents which one will you use for cleaning clothes "

Take 10 mL distilled water in a test tube and take the same volume of hard water in another test tube. Add a few drops of soap solution to both the test tubes and shake well. Do both the test tubes contain the same quantity of foam? Which test tube contains more foam? What do you infer?

In order to wash clothes with water containing dissolved calcium hydrogen carbonates, which cleaning agent will you prefer and why? Soaps or synthetic detergents give one advantage of soaps over synthetic detergents?

Monosaccharides containing an aldehyde group are called aldoses while those containing aketo group are called ketoses. The aldehyde group is always present at C_1 while the keto group is usually present at C_2 . All monosaccharides containing five and six carbon atoms have cyclic structures, furnaose (five membered) and pyranose (six membered). During ring formation, C_1 in aldoses and C_2 in ketoses becomes chiral and hence all these monosaccharides exist in two stereoisomeric forms called the alpha -anomer and the beta -anomer while C_1 and C_2 are called glycosidic or anomeric carbon atoms. In contrast, stereoisomers, which differ in configuration at any other chiral carbon other than the glycosidic carbon are called epimers. Two molecules of the same or different monosaccharides combine together through glycosidic linkage to form disaccharides. All monosaccharides (aldoses and ketoses) and most disaccharides reduce Tollens'reagent and Fehling's solution, undergo mutarotation and form osazones. Which of the following pairs give positive Tollens' test?
