To identify the correct pairs of processes that are the reverse of each other in terms of initial reactant and final product. Concept introduction: Monosaccharides are the simplest carbohydrate units which cannot be hydrolyzed further to give the smallest units. Glucose is a monosaccharide with the molecular formula C 6 H 12 O 6 . Polysaccharides contain many carbohydrate units that vary from 100 to 50,000 monosaccharide units. Glycogen is a polysaccharide of glucose. It serves as a form of carbohydrate storage in humans and animals. Glycogen is a source of glucose in humans and animals. A reactant is defined as the substance that is initially present in the chemical reaction and gets consumed to form a new substance. A product is defined as the substance that is formed after the completion of a chemical reaction.

Question

Consider the reaction of a propanoate ester with hydroxide ion shown below. A series of four alcohol leaving groups were tested to determine which would be the best leaving group. Based on the pKa values of the alcohols, predict which alcohol would produce the fastest hydrolysis reaction. HO FOR A Alcohol I, pKa =16.0 B Alcohol II, pKa =10.0 C Alcohol III, pKa = 7.2 + ROH D Alcohol IV, pKa = 6.6

Interpretation Introduction

Interpretation: To identify the correct pairs of processes that are the reverse of each other in terms of initial reactant and final product.

Concept introduction: Monosaccharides are the simplest carbohydrate units which cannot be hydrolyzed further to give the smallest units. Glucose is a monosaccharide with the molecular formula C6H12O6.

Polysaccharides contain many carbohydrate units that vary from 100 to 50,000 monosaccharide units. Glycogen is a polysaccharide of glucose. It serves as a form of carbohydrate storage in humans and animals. Glycogen is a source of glucose in humans and animals.

A reactant is defined as the substance that is initially present in the chemical reaction and gets consumed to form a new substance. A product is defined as the substance that is formed after the completion of a chemical reaction.
