Q. The rate of the reaction, 2A+B gives products is given by rate expression, rate = k(A)^1.5 (B)^0.5. If (A) is 2molar and (B) is 100molar, then the order of reaction will be?

Q. The following carbohydrate is

(IIT-JEE, 2011)

1. a ketohexose
2. an aldohexose
3. an $\alpha$ - furanose
4. an $\alpha$ - pyranose

Q. Which is not true for reducing and non reducing sugars?

1. Both depends on the position of linkage between two monosaccharides unit
2. Sucrose is a non reducing sugar, as linkage involves the carbonyl functional group of both monosaccharides units
3. Maltose and Lactose are reducing sugar, as one of the carbonyl functional group in any one of the monosaccharides unit is free
4. Maltose is reducing sugar while lactose and sucrose both are non reducing sugar
