Isotactic or syndiotactic polymers often more attractive for materials development. Concept introduction: An isotactic polymer is compound that is formed by the arrangement of monomers in the same pattern of its chain backbone. It indicates that all groups attached to carbon atom are pointing towards backward. Vinyl chloride follows the same sequence while forming the polymer and produces the isotactic PVC. A sydiotactic is the direction of adjacent molecules alternatively arranged (backward and front) to form a polymer.

Interpretation Introduction

Interpretation:

Isotactic or syndiotactic polymers often more attractive for materials development.

Concept introduction:

An isotactic polymer is compound that is formed by the arrangement of monomers in the same pattern of its chain backbone. It indicates that all groups attached to carbon atom are pointing towards backward. Vinyl chloride follows the same sequence while forming the polymer and produces the isotactic PVC. A sydiotactic is the direction of adjacent molecules alternatively arranged (backward and front) to form a polymer.

Here's a wild molecule: disulfur dinitride (S2N2). It can be isolated as a crystalline solid, but it is unstable (explosive). Therefore, it must to be handled carefully in an inert atmosphere free of oxygen. X-ray diffraction measurements of the crystalline solid indicate the atoms are arranged in a square with the sulfur atoms on opposite corners and the nitrogen atoms on the remaining opposite corners. Consider the bonding in this unusual molecule. a. Determine the best Lewis structure representation for S2N2. Include the formal charges on each atom in the structure. b. Determine the valence bonding theory predictions for hybridization at each atom in S2N2. The bond angles in S2N2 have been measured by X-ray diffraction and are all approximately 90°. Does valence bond theory do a good job of predicting this observation? Consider the geometry and bonding of S2N2 computed using molecular orbital theory. The results are shown below. Identify the orbital character of the HOMO(-2),…
