The validation about the amylose form of starch being a homopolysaccharide has to be predicted. Concept introduction: A polymer in which many monosaccharide units are joined together by glycosidic linkages is known as a polysaccharide. Starch is a storage polysaccharide found in plant cells. Starch contains two different polyglucose polysaccharides: amylose and amylopectin. If all monosaccharide units are same, then the polysaccharide is known as homopolysaccharide.

Question

Which of the following would you expect to be antiaromatic? Please provide a detailed explanation.

Answer 1

Question

Definition Definition Monomer units that are not only combined in the linear chain but are also attached through branches of different lengths along the main chain. Branched-chain polymers have a lower density, lower melting point, and lower tensile strength compared to linear chain polymers because branched-chain does not pack well. Examples of branched-chain polymers are amylopectin and glycogen.
