Apolysaccharide of unknown structure was isolated, subjected to exhaustive methylation (which will modify free hydroxyls), and hydrolyzed (also see chap 8 #6). analysis of the products revealed the following three methylated sugars in the ratio 20: 1: 1. the sugars were 2,3,4-tri-o-methyl-d-glucose, 2,4-di-o-methyl-d-glucose, and 2,3,4,6-tetra-o-methyl-dglucose. what is the structure of the polysaccharide?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
