Explanation The total number of valence electrons in ribose sugar is the sum of valence electrons of five carbon atoms, valence electrons of five oxygen atoms and valence electrons of ten hydrogen atoms. There are four valence electrons in each carbon atom, six valence electrons in each oxygen atom, and one valence electron in each hydrogen atom. Therefore, the total number of valence electrons in deoxyribose sugar is 58 . The Lewis diagram of deoxyribose sugar is shown below.

Carbohydrates

Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.

Starch

Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.

Mutarotation

The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of th…

L Sugar

A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotat…

Question

Chapter 22, Problem 49E

Interpretation Introduction

Interpretation:

The Lewis diagram for the sugar ribose is to be drawn. The difference between sugar ribose and deoxyribose sugar is to be stated.

Concept introduction:

The Lewis structure shows the connectivity between atoms by identifying the lone pairs of electrons in a compound. Lewis structures are also known as Lewis dot structures. The valence electrons around an atom are shown by dots. Bonds between atoms are shown by lines and the lone pair of electrons is shown by a pair of dots.
