Results

#1. (19) The response of glucose to esterification and reduction reaction by Fehling's solution

a)because it contains aldehyde group so it has ability to react with mineral acid to form ester and also it responses to the reduction reaction because it contains hydroxyl group [-OH] that can be reduced into hydroxyl group

b)Because it contains hydroxyl group so it has ability to react with organic acid to form ester and also it responses to the reduction reaction because it contains aldehyde group [-CHO] that can be reduced into hydroxyl group

c)because it contains hydroxyl group so it has ability to react with mineral acid to form ester and also it responses to the reduction reaction because it contains aldehyde group [-CHO] that can be reduced into hydroxyl group

d)there is no correct answer

#2. (20) The similarity of acetone and fructose in some chemical reactions.

a)because both of them have carbonyl group and hydroxyl group

b)because both of them have hydroxyl group

c)Because both of them have carbonyl group

d)there is no correct answer

#3. (21) The aqueous solution of sodium phenoxide turns the litmus paper into blue.

a)Because it composed of strong base with weak acid and its pH>7

b)because it composed of weak base with strong acid and its pH<7

c)because it composed of weak base with weak acid and its pH=7

d)because it composed of strong base with strong acid and its pH=7
